Support Mantine development

You can now sponsor Mantine development with OpenCollective. All funds are used to improve Mantine and create new features and components.

TreeSelect component

New TreeSelect component allows picking one or more values from hierarchical tree data. It supports three selection modes: single, multiple, and checkbox (with parent-child cascade):

import { TreeSelect } from '@mantine/core';
import { data } from './data';

function Demo() {
  return (
    <TreeSelect
      label="Your favorite item"
      placeholder="Pick value"
      data={data}
    />
  );
}

Tree select Combobox examples

New Combobox examples showing how to build tree select components from Combobox primitives with connecting lines, expand/collapse chevrons, and proper indentation:

Notifications swipe dismissal

@mantine/notifications now supports dismissing notifications by dragging them left or right, and with horizontal scroll swipe while hovered. Both interactions can be disabled on Notifications, and individual items can opt out with allowClose: false.

import { Button } from '@mantine/core';
import { notifications } from '@mantine/notifications';

function Demo() {
  return (
    <Button
      onClick={() =>
        notifications.show({
          title: 'Default notification',
          message: 'Do not forget to star Mantine on GitHub! 🌟',
        })
      }
    >
      Show notification
    </Button>
  );
}

use-drag hook

New use-drag hook handles pointer drag gestures with movement tracking, velocity, direction and axis constraints. It uses the Pointer Events API and works with both mouse and touch input:

import { useState } from 'react';
import { Button, Group, Paper, Text } from '@mantine/core';
import { useDrag } from '@mantine/hooks';

interface NotificationItem {
  id: number;
  text: string;
}

function SwipeNotification({
  notification,
  onDismiss,
}: {
  notification: NotificationItem;
  onDismiss: (id: number) => void;
}) {
  const [offset, setOffset] = useState(0);
  const [dismissed, setDismissed] = useState(false);

  const { ref, active } = useDrag(
    (state) => {
      if (state.last) {
        const shouldDismiss =
          Math.abs(state.movement[0]) > 120 || state.velocity[0] > 0.5;
        if (shouldDismiss) {
          setDismissed(true);
          setTimeout(() => onDismiss(notification.id), 300);
        } else {
          setOffset(0);
        }
      } else {
        setOffset(state.movement[0]);
      }
    },
    { axis: 'x', threshold: 5, filterTaps: true }
  );

  return (
    <Paper
      ref={ref}
      p="sm"
      mb="xs"
      withBorder
      radius="md"
      style={{
        transform: dismissed
          ? `translateX(${offset > 0 ? 400 : -400}px)`
          : `translateX(${offset}px)`,
        opacity: dismissed ? 0 : 1 - Math.min(Math.abs(offset) / 200, 1) * 0.6,
        transition: active ? 'none' : 'transform 300ms ease, opacity 300ms ease',
        cursor: active ? 'grabbing' : 'grab',
        touchAction: 'pan-y',
        userSelect: 'none',
      }}
    >
      {notification.text}
    </Paper>
  );
}

const initialItems: NotificationItem[] = [
  { id: 1, text: 'New message from Alice' },
  { id: 2, text: 'Build succeeded' },
  { id: 3, text: 'Deployment complete' },
  { id: 4, text: 'Review requested' },
];

function Demo() {
  const [notifications, setNotifications] = useState(initialItems);

  return (
    <div style={{ height: 300 }}>
      {notifications.map((n) => (
        <SwipeNotification
          key={n.id}
          notification={n}
          onDismiss={(id) =>
            setNotifications((items) => items.filter((item) => item.id !== id))
          }
        />
      ))}

      {notifications.length === 0 && (
        <Text ta="center" c="dimmed" py="md">All cleared!</Text>
      )}

      <Group justify="center" mt="md">
        <Button onClick={() => setNotifications(initialItems)}>
          Reset
        </Button>
      </Group>
    </div>
  );
}

InlineDateTimePicker component

New InlineDateTimePicker component renders a calendar with a time picker inline, without a dropdown. It supports both default and range modes:

import { InlineDateTimePicker } from '@mantine/dates';

function Demo() {
  return <InlineDateTimePicker />;
}

Set type="range" to select a date and time range with two time inputs:

import { InlineDateTimePicker } from '@mantine/dates';

function Demo() {
  return <InlineDateTimePicker type="range" />;
}

DateTimePicker range support

DateTimePicker now supports type="range" to select a date and time range. In range mode, two time inputs are displayed in the dropdown for start and end times:

import { DateTimePicker } from '@mantine/dates';

function Demo() {
  return (
    <DateTimePicker
      type="range"
      label="Pick dates and times range"
      placeholder="Pick dates and times range"
    />
  );
}

DateTimePicker valueFormat function

DateTimePicker valueFormat prop now accepts a function in addition to a dayjs format string. The callback receives the value as a YYYY-MM-DD HH:mm:ss string and returns the formatted value, which is useful for cases that cannot be expressed with a dayjs format string:

import dayjs from 'dayjs';
import { DateTimePicker } from '@mantine/dates';

function Demo() {
  return (
    <DateTimePicker
      valueFormat={(date) => dayjs(date).format('dddd, MMMM D [at] h:mm A')}
      defaultValue="2024-04-11 14:45:00"
      label="Pick date and time"
      placeholder="Pick date and time"
    />
  );
}

RollingNumber component

New RollingNumber component animates value changes with rolling digit transitions. Each digit independently rolls to its new position when the value changes:

import { useState } from 'react';
import { Button, Group, RollingNumber } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState(1234);

  return (
    <>
      <RollingNumber value={value} fz="36px" />
      <Group mt="md">
        <Button onClick={() => setValue((v) => v + 1)}>Increment</Button>
        <Button onClick={() => setValue((v) => v - 1)}>Decrement</Button>
        <Button onClick={() => setValue(Math.floor(Math.random() * 10000))}>Random</Button>
      </Group>
    </>
  );
}

MaskInput improvements

MaskInput now supports a resetRef prop that assigns a function that clears the input value imperatively. This is useful because MaskInput is uncontrolled internally, so setting value from a parent does not clear it:

import { useRef } from 'react';
import { MaskInput, Button, Group } from '@mantine/core';

function Demo() {
  const resetRef = useRef<() => void>(null);

  return (
    <>
      <MaskInput
        label="Phone number"
        placeholder="(___) ___-____"
        mask="(999) 999-9999"
        resetRef={resetRef}
      />

      <Group mt="md">
        <Button onClick={() => resetRef.current?.()}>Reset</Button>
      </Group>
    </>
  );
}

MaskInput integration with use-form is now documented. Use defaultValue to seed the initial value and onChangeRaw to write the raw value to form state:

import { Button, MaskInput } from '@mantine/core';
import { useForm } from '@mantine/form';

function Demo() {
  const form = useForm({
    mode: 'uncontrolled',
    initialValues: { phone: '' },
  });

  return (
    <form onSubmit={form.onSubmit((values) => console.log(values))}>
      <MaskInput
        mask="(999) 999-9999"
        placeholder="(___) ___-____"
        label="Phone"
        onChangeRaw={(raw) => form.setFieldValue('phone', raw)}
      />

      <Button type="submit" mt="md">
        Submit
      </Button>
    </form>
  );
}

SankeyChart component

New SankeyChart component visualizes flow between nodes as a Sankey diagram where the width of each link is proportional to the flow value:

// Demo.tsx
import { SankeyChart } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return <SankeyChart data={data} />;
}

// data.ts
export const data = {
  nodes: [
    { name: 'Visit' },
    { name: 'Direct-Favourite' },
    { name: 'Page-Click' },
    { name: 'Detail-Favourite' },
    { name: 'Lost' },
  ],
  links: [
    { source: 0, target: 1, value: 3728.3 },
    { source: 0, target: 2, value: 354170 },
    { source: 2, target: 3, value: 62429 },
    { source: 2, target: 4, value: 291741 },
  ],
};

Reorder pills in MultiSelect and TagsInput

MultiSelect and TagsInput now support reordering selected pills. Set the new withPillsReorder prop to enable it. Pills can be reordered with a mouse (drag-and-drop) or keyboard:

  • Pills are not part of the Tab order. ArrowLeft from the input (caret at start) moves focus to the last pill.
  • ArrowLeft and ArrowRight navigate between pills (RTL-aware). ArrowRight on the last pill returns focus to the input.
  • Alt + ArrowLeft and Alt + ArrowRight reorder the focused pill (RTL-aware). Focus follows the moved pill so chained moves work.

Reordering is automatically disabled when disabled or readOnly is set. Custom pill renderers receive a reorderProps payload that can be spread onto the pill element to keep reordering working:

import { useState } from 'react';
import { MultiSelect } from '@mantine/core';

function Demo() {
  const [value, setValue] = useState(['React', 'Angular', 'Vue']);

  return (
    <MultiSelect
      label="Drag pills to reorder"
      description="Selected values can be reordered by dragging pills"
      placeholder="Pick value"
      data={['React', 'Angular', 'Vue', 'Svelte', 'Solid', 'Ember']}
      value={value}
      onChange={setValue}
      withPillsReorder
    />
  );
}

Restrict Tree drop targets

Tree component now supports restricting drop targets with the new allowDrop prop. The callback receives { draggedNode, targetNode, position } and returning false hides the drop indicator and rejects the drop, so users get proper visual feedback before releasing:

import { useState } from 'react';
import { CaretDownIcon } from '@phosphor-icons/react';
import { Group, moveTreeNode, RenderTreeNodePayload, Tree, TreeNodeData } from '@mantine/core';

const data: TreeNodeData[] = [
  {
    label: 'Pages',
    value: 'pages',
    children: [
      { label: 'index.tsx', value: 'pages/index.tsx' },
      { label: 'about.tsx', value: 'pages/about.tsx' },
    ],
  },
  {
    label: 'Components (locked)',
    value: 'components',
    children: [
      { label: 'Header.tsx', value: 'components/Header.tsx' },
      { label: 'Footer.tsx', value: 'components/Footer.tsx' },
    ],
  },
  { label: 'package.json', value: 'package.json' },
];

function Leaf({ node, expanded, hasChildren, elementProps }: RenderTreeNodePayload) {
  return (
    <Group gap={5} {...elementProps}>
      {hasChildren && (
        <CaretDownIcon
          size={18}
          style={{ transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)' }}
        />
      )}
      <span>{node.label}</span>
    </Group>
  );
}

function Demo() {
  const [treeData, setTreeData] = useState(data);

  return (
    <Tree
      data={treeData}
      // Forbid dropping into or onto "components" branch
      allowDrop={({ draggedNode, targetNode, position }) => {
        if (draggedNode === 'components' || draggedNode.startsWith('components/')) {
          return false;
        }

        if (targetNode === 'components' && position === 'inside') {
          return false;
        }

        return !targetNode.startsWith('components/');
      }}
      onDragDrop={(payload) =>
        setTreeData((current) => moveTreeNode(current, payload))
      }
      renderNode={(payload) => <Leaf {...payload} />}
    />
  );
}

Tree drag handle

Tree component now supports restricting drag initiation to a dedicated handle with the new withDragHandle prop. The handle spreads dragHandleProps from the renderNode payload. This is useful when a node contains interactive controls (inputs, buttons) that would otherwise interfere with dragging:

import { useState } from 'react';
import { CaretDownIcon, DotsSixVerticalIcon } from '@phosphor-icons/react';
import { Group, moveTreeNode, RenderTreeNodePayload, Tree, TreeNodeData } from '@mantine/core';

const data: TreeNodeData[] = [
  {
    label: 'Pages',
    value: 'pages',
    children: [
      { label: 'index.tsx', value: 'pages/index.tsx' },
      { label: 'about.tsx', value: 'pages/about.tsx' },
    ],
  },
  {
    label: 'Components',
    value: 'components',
    children: [
      { label: 'Header.tsx', value: 'components/Header.tsx' },
      { label: 'Footer.tsx', value: 'components/Footer.tsx' },
    ],
  },
  { label: 'package.json', value: 'package.json' },
];

function Leaf({ node, expanded, hasChildren, elementProps, dragHandleProps }: RenderTreeNodePayload) {
  return (
    <Group gap={4} {...elementProps}>
      <DotsSixVerticalIcon
        {...dragHandleProps}
        size={16}
        style={{ cursor: 'grab' }}
      />
      {hasChildren && (
        <CaretDownIcon
          size={18}
          style={{ transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)' }}
        />
      )}
      <span>{node.label}</span>
    </Group>
  );
}

function Demo() {
  const [treeData, setTreeData] = useState(data);

  return (
    <Tree
      data={treeData}
      withDragHandle
      onDragDrop={(payload) =>
        setTreeData((current) => moveTreeNode(current, payload))
      }
      renderNode={(payload) => <Leaf {...payload} />}
    />
  );
}

Shared default props for all inputs

Default props set on Input and Input.Wrapper in theme.components now cascade to every component built on top of them (TextInput, Textarea, NumberInput, Select, DateInput, and others). This makes it possible to apply shared size, radius, variant, withAsterisk and other props to all inputs at once, while still overriding individual components with their own default props:

import { TextInput, NumberInput, NativeSelect, MantineProvider, createTheme, Input } from '@mantine/core';

const theme = createTheme({
  components: {
    Input: Input.extend({
      defaultProps: {
        size: 'md',
        radius: 'md',
      },
    }),

    InputWrapper: Input.Wrapper.extend({
      defaultProps: {
        withAsterisk: true,
      },
    }),

    NumberInput: NumberInput.extend({
      defaultProps: {
        size: 'lg',
      },
    }),
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <TextInput label="Text input" placeholder="Inherits size and radius from Input" />

      <NativeSelect
        mt="md"
        label="Native select"
        data={['React', 'Angular', 'Vue', 'Svelte']}
      />

      <NumberInput mt="md" label="Number input" placeholder="Overrides shared size with lg" />
    </MantineProvider>
  );
}

Per-day business hours in WeekView

WeekView businessHours prop now accepts a per-day object keyed by day of the week (0 – Sunday, 6 – Saturday) in addition to the shared [start, end] tuple. Days missing from the object or set to null are rendered as fully outside business hours, making it easy to model partial workdays and non-working days:

import { WeekView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <WeekView
      date={new Date()}
      events={events}
      highlightBusinessHours
      businessHours={{
        1: ['09:00:00', '17:00:00'],
        2: ['09:00:00', '17:00:00'],
        3: ['09:00:00', '17:00:00'],
        4: ['09:00:00', '17:00:00'],
        5: ['09:00:00', '13:00:00'],
      }}
      startTime="07:00:00"
      endTime="20:00:00"
    />
  );
}

Support Mantine development

You can now sponsor Mantine development with OpenCollective. All funds are used to improve Mantine and create new features and components.

deduplicateInlineStyles

New deduplicateInlineStyles prop on MantineProvider enables React 19 style tag deduplication for responsive style props. When many components share the same responsive style prop values, only a single <style /> tag is generated and hoisted to <head /> instead of each component injecting its own:

import { MantineProvider } from '@mantine/core';

function Demo() {
  return (
    <MantineProvider deduplicateInlineStyles>
      {/* Your app here */}
    </MantineProvider>
  );
}

This can significantly improve performance when rendering large lists of components with identical responsive style props. See the styles performance guide for more details.

use-mask hook

New use-mask hook attaches real-time input masking to any <input> element via a ref callback. It formats user input against a defined pattern and exposes both the masked display value and the raw unmasked value. The hook supports built-in and custom tokens, dynamic masks, character transforms, optional segments, and regex array format:

import { TextInput, Text } from '@mantine/core';
import { useMask } from '@mantine/hooks';

function Demo() {
  const { ref, value, rawValue } = useMask({ mask: '(999) 999-9999' });

  return (
    <>
      <TextInput ref={ref} label="Phone number" placeholder="(___) ___-____" />
      <Text size="sm" mt="sm">Masked value: {value}</Text>
      <Text size="sm">Raw value: {rawValue}</Text>
    </>
  );
}

MaskInput component

New MaskInput component is a wrapper around use-mask hook that provides all standard input props (label, description, error, etc.) and supports all mask options:

import { MaskInput } from '@mantine/core';

function Demo() {
  return (
    <MaskInput
       variant="default" size="sm" radius="md" label="Input label" withAsterisk={false} description="Input description" error=""
      mask="(999) 999-9999"
      placeholder="(___) ___-____"
    />
  );
}

Treemap component

New Treemap component displays hierarchical data as a set of nested rectangles. It is based on the Treemap recharts component:

// Demo.tsx
import { Treemap } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return <Treemap data={data} />;
}

// data.ts
export const data = [
  {
    name: 'Frontend',
    color: 'blue.8',
    children: [
      { name: 'React', value: 400 },
      { name: 'Vue', value: 200 },
      { name: 'Angular', value: 150 },
    ],
  },
  {
    name: 'Backend',
    color: 'teal.8',
    children: [
      { name: 'Node', value: 300 },
      { name: 'Python', value: 250 },
      { name: 'Go', value: 100 },
    ],
  },
  {
    name: 'Mobile',
    color: 'red.8',
    children: [
      { name: 'React Native', value: 200 },
      { name: 'Flutter', value: 180 },
    ],
  },
];

TimePicker duration type

TimePicker component now supports type="duration" prop that allows entering durations that exceed 24 hours. In this mode, the hours field has no upper limit and the input width adjusts dynamically based on the entered value:

import { TimePicker } from '@mantine/dates';

function Demo() {
  return <TimePicker label="Enter duration" type="duration" withSeconds />;
}

Heatmap legend

Heatmap component now supports withLegend prop that displays a color legend below the chart. Use legendLabels prop to customize labels (default: ['Less', 'More']):

// Demo.tsx
import { Heatmap } from '@mantine/charts';
import { data } from './data';

function Demo() {
  return (
    <Heatmap
      data={data}
      startDate="2024-02-16"
      endDate="2025-02-16"
      withMonthLabels
      withWeekdayLabels
      withLegend
    />
  );
}

// data.ts
export const data = ${JSON.stringify(data, null, 2)};

MonthPicker and YearPicker presets

MonthPicker and YearPicker components now support presets prop that allows adding predefined values to pick from. Presets are also available in MonthPickerInput and YearPickerInput components:

import dayjs from 'dayjs';
import { MonthPicker } from '@mantine/dates';

function Demo() {
  return (
    <MonthPicker
      presets={[
        { value: dayjs().startOf('month').format('YYYY-MM-DD'), label: 'This month' },
        { value: dayjs().add(1, 'month').startOf('month').format('YYYY-MM-DD'), label: 'Next month' },
        { value: dayjs().subtract(1, 'month').startOf('month').format('YYYY-MM-DD'), label: 'Last month' },
        { value: dayjs().add(6, 'month').startOf('month').format('YYYY-MM-DD'), label: 'In 6 months' },
        { value: dayjs().add(1, 'year').startOf('month').format('YYYY-MM-DD'), label: 'Next year' },
        { value: dayjs().subtract(1, 'year').startOf('month').format('YYYY-MM-DD'), label: 'Last year' },
      ]}
    />
  );
}

use-roving-index hook

New use-roving-index hook implements the roving tabindex keyboard navigation pattern. It manages tabIndex state for a group of focusable elements, handles arrow key navigation with disabled item skipping, and supports both 1D lists and 2D grids:

import { Button, Group } from '@mantine/core';
import { useRovingIndex } from '@mantine/hooks';

const items = ['Bold', 'Italic', 'Underline', 'Strikethrough', 'Code'];

function Demo() {
  const { getItemProps } = useRovingIndex({
    total: items.length,
    orientation: 'horizontal',
    loop: true,
  });

  return (
    <Group gap="xs">
      {items.map((item, index) => (
        <Button key={item} variant="default" {...getItemProps({ index })}>
          {item}
        </Button>
      ))}
    </Group>
  );
}

Tree drag and drop

Tree component now supports drag-and-drop reordering of nodes. Provide onDragDrop callback to enable it, and use the moveTreeNode utility to update data based on the result:

import { useState } from 'react';
import { CaretDownIcon } from '@phosphor-icons/react';
import { Group, moveTreeNode, RenderTreeNodePayload, Tree, TreeNodeData } from '@mantine/core';

const data: TreeNodeData[] = [
  {
    label: 'Pages',
    value: 'pages',
    children: [
      { label: 'index.tsx', value: 'pages/index.tsx' },
      { label: 'about.tsx', value: 'pages/about.tsx' },
      { label: 'contact.tsx', value: 'pages/contact.tsx' },
    ],
  },
  {
    label: 'Components',
    value: 'components',
    children: [
      { label: 'Header.tsx', value: 'components/Header.tsx' },
      { label: 'Footer.tsx', value: 'components/Footer.tsx' },
      { label: 'Sidebar.tsx', value: 'components/Sidebar.tsx' },
    ],
  },
  { label: 'package.json', value: 'package.json' },
  { label: 'tsconfig.json', value: 'tsconfig.json' },
];

function Leaf({ node, expanded, hasChildren, elementProps }: RenderTreeNodePayload) {
  return (
    <Group gap={5} {...elementProps}>
      {hasChildren && (
        <CaretDownIcon
          size={18}
          style={{ transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)' }}
        />
      )}
      <span>{node.label}</span>
    </Group>
  );
}

function Demo() {
  const [treeData, setTreeData] = useState(data);

  return (
    <Tree
      data={treeData}
      onDragDrop={(payload) =>
        setTreeData((current) => moveTreeNode(current, payload))
      }
      renderNode={(payload) => <Leaf {...payload} />}
    />
  );
}

Tree async loading

Tree now supports lazy loading of children. Set hasChildren: true on a node without providing children – when the node is expanded for the first time, onLoadChildren callback passed to useTree is called. Use mergeAsyncChildren utility to splice loaded children into your data:

import { useState } from 'react';
import { CaretDownIcon, SpinnerIcon } from '@phosphor-icons/react';
import {
  Group,
  mergeAsyncChildren,
  RenderTreeNodePayload,
  Tree,
  TreeNodeData,
  useTree,
} from '@mantine/core';

const initialData: TreeNodeData[] = [
  { label: 'Documents', value: 'documents', hasChildren: true },
  { label: 'Photos', value: 'photos', hasChildren: true },
  { label: 'README.md', value: 'readme' },
];

// Simulates an API call to load children
async function fetchChildren(parentValue: string): Promise<TreeNodeData[]> {
  await new Promise((resolve) => setTimeout(resolve, 1000));
  return [
    { label: `${parentValue}/file-1.txt`, value: `${parentValue}/file-1.txt` },
    { label: `${parentValue}/file-2.txt`, value: `${parentValue}/file-2.txt` },
    {
      label: `${parentValue}/subfolder`,
      value: `${parentValue}/subfolder`,
      hasChildren: true,
    },
  ];
}

function Leaf({ node, expanded, hasChildren, elementProps, isLoading }: RenderTreeNodePayload) {
  return (
    <Group gap={5} wrap="nowrap" {...elementProps}>
      {isLoading ? (
        <SpinnerIcon size={18} style={{ animation: 'spin 1s linear infinite', flexShrink: 0 }} />
      ) : (
        hasChildren && (
          <CaretDownIcon
            size={18}
            style={{ transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)', flexShrink: 0 }}
          />
        )
      )}
      <span style={{ overflow: 'hidden', textOverflow: 'ellipsis', whiteSpace: 'nowrap' }}>
        {node.label}
      </span>
    </Group>
  );
}

function Demo() {
  const [data, setData] = useState(initialData);
  const tree = useTree({
    onLoadChildren: async (value) => {
      const children = await fetchChildren(value);
      setData((prev) => mergeAsyncChildren(prev, value, children));
    },
  });

  return (
    <Tree
      data={data}
      tree={tree}
      renderNode={(payload) => <Leaf {...payload} />}
    />
  );
}

Tree search and filtering

Tree now includes filterTreeData utility to filter tree data based on a search query. Matching nodes and their ancestors are preserved in the result. You can provide a custom filter function for advanced matching (for example, fuzzy search with fuse.js):

import { useMemo, useState } from 'react';
import {
  filterTreeData,
  getTreeExpandedState,
  TextInput,
  Tree,
  TreeNodeData,
  useTree,
} from '@mantine/core';

const data: TreeNodeData[] = [
  {
    label: 'src',
    value: 'src',
    children: [
      {
        label: 'components',
        value: 'src/components',
        children: [
          { label: 'Accordion.tsx', value: 'src/components/Accordion.tsx' },
          { label: 'Tree.tsx', value: 'src/components/Tree.tsx' },
          { label: 'Button.tsx', value: 'src/components/Button.tsx' },
          { label: 'Input.tsx', value: 'src/components/Input.tsx' },
        ],
      },
      {
        label: 'hooks',
        value: 'src/hooks',
        children: [
          { label: 'use-debounce.ts', value: 'src/hooks/use-debounce.ts' },
          { label: 'use-media-query.ts', value: 'src/hooks/use-media-query.ts' },
        ],
      },
    ],
  },
  {
    label: 'public',
    value: 'public',
    children: [
      { label: 'favicon.ico', value: 'public/favicon.ico' },
      { label: 'logo.svg', value: 'public/logo.svg' },
    ],
  },
  { label: 'package.json', value: 'package.json' },
  { label: 'tsconfig.json', value: 'tsconfig.json' },
];

function Demo() {
  const [search, setSearch] = useState('');
  const tree = useTree();

  const filteredData = useMemo(
    () => filterTreeData(data, search),
    [search]
  );

  const handleSearchChange = (value: string) => {
    setSearch(value);
    if (value.trim()) {
      const next = filterTreeData(data, value);
      tree.setExpandedState(getTreeExpandedState(next, '*'));
    } else {
      tree.collapseAllNodes();
    }
  };

  return (
    <div>
      <TextInput
        placeholder="Search..."
        mb="sm"
        value={search}
        onChange={(event) => handleSearchChange(event.currentTarget.value)}
      />
      <Tree data={filteredData} tree={tree} />
    </div>
  );
}

Tree connecting lines

Tree now supports withLines prop to display connecting lines showing parent-child relationships. Lines adapt to levelOffset spacing automatically:

import { getTreeExpandedState, Tree, useTree } from '@mantine/core';
import { data } from './data';

function Demo() {
  const tree = useTree({
    initialExpandedState: getTreeExpandedState(data, '*'),
  });

  return <Tree data={data} tree={tree} withLines />;
}

Tree virtualization

Tree now provides flattenTreeData utility and FlatTreeNode component for virtualized rendering of large trees. The component does not depend on any virtualization library – you supply one yourself (e.g., @tanstack/react-virtual):

import { useMemo, useRef } from 'react';
import { useVirtualizer } from '@tanstack/react-virtual';
import {
  FlatTreeNode,
  flattenTreeData,
  getTreeExpandedState,
  TreeNodeData,
  useTree,
} from '@mantine/core';

const ITEM_HEIGHT = 30;

function generateTreeData(count: number): TreeNodeData[] {
  const result: TreeNodeData[] = [];
  let id = 0;

  function addChildren(
    parent: TreeNodeData[],
    depth: number,
    remaining: { count: number }
  ) {
    const childCount = depth === 0 ? 20 : Math.floor(Math.random() * 8) + 2;

    for (let i = 0; i < childCount && remaining.count > 0; i++) {
      id++;
      remaining.count--;
      const hasChild =
        depth < 3 && remaining.count > 0 && Math.random() > 0.3;
      const node: TreeNodeData = {
        label: `${hasChild ? 'Folder' : 'File'} ${id}`,
        value: `node-${id}`,
        children: hasChild ? [] : undefined,
      };

      if (hasChild) {
        addChildren(node.children!, depth + 1, remaining);
      }

      parent.push(node);
    }
  }

  addChildren(result, 0, { count });
  return result;
}

const largeData = generateTreeData(2000);
const initialExpandedState = getTreeExpandedState(largeData, '*');

function Demo() {
  const tree = useTree({
    initialExpandedState,
  });

  const flatList = useMemo(
    () => flattenTreeData(largeData, tree.expandedState),
    [tree.expandedState]
  );

  const scrollParentRef = useRef<HTMLDivElement>(null);

  const virtualizer = useVirtualizer({
    count: flatList.length,
    getScrollElement: () => scrollParentRef.current,
    estimateSize: () => ITEM_HEIGHT,
    overscan: 20,
  });

  return (
    <div ref={scrollParentRef} style={{ height: 400, overflow: 'auto' }}>
      <div
        data-tree-root
        role="tree"
        style={{
          height: virtualizer.getTotalSize(),
          position: 'relative',
        }}
      >
        {virtualizer.getVirtualItems().map((virtualItem) => (
          <FlatTreeNode
            key={flatList[virtualItem.index].node.value}
            {...flatList[virtualItem.index]}
            tree={tree}
            expandOnClick
            selectOnClick
            tabIndex={virtualItem.index === 0 ? 0 : -1}
            style={{
              position: 'absolute',
              top: 0,
              left: 0,
              width: '100%',
              height: virtualItem.size,
              transform: `translateY(${virtualItem.start}px)`,
            }}
          />
        ))}
      </div>
    </div>
  );
}

Tree checkStrictly mode

useTree hook now supports checkStrictly option. When enabled, checking a parent node does not affect children and vice versa – each node's checked state is fully independent:

import { CaretDownIcon } from '@phosphor-icons/react';
import { Checkbox, Group, RenderTreeNodePayload, Tree, useTree } from '@mantine/core';
import { data } from './data';

const renderTreeNode = ({
  node,
  expanded,
  hasChildren,
  elementProps,
  tree,
}: RenderTreeNodePayload) => {
  const checked = tree.isNodeChecked(node.value);

  return (
    <Group gap="xs" {...elementProps}>
      <Checkbox.Indicator
        checked={checked}
        onClick={() =>
          checked
            ? tree.uncheckNode(node.value)
            : tree.checkNode(node.value)
        }
      />

      <Group gap={5} onClick={() => tree.toggleExpanded(node.value)}>
        <span>{node.label}</span>

        {hasChildren && (
          <CaretDownIcon
            size={14}
            style={{
              transform: expanded ? 'rotate(180deg)' : 'rotate(0deg)',
            }}
          />
        )}
      </Group>
    </Group>
  );
};

function Demo() {
  const tree = useTree({ checkStrictly: true });
  return (
    <Tree
      data={data}
      tree={tree}
      levelOffset={23}
      expandOnClick={false}
      renderNode={renderTreeNode}
    />
  );
}

Slider startPointValue

Slider component now supports startPointValue prop that changes the origin of the filled bar. When set, the bar extends from the given value toward the current value – to the left for values below the start point and to the right for values above it:

import { Slider } from '@mantine/core';

function Demo() {
  return (
    <Slider
      startPointValue={0}
      min={-100}
      max={100}
      defaultValue={40}
      marks={[
        { value: -100, label: '-100' },
        { value: -50, label: '-50' },
        { value: 0, label: '0' },
        { value: 50, label: '50' },
        { value: 100, label: '100' },
      ]}
    />
  );
}

WeekView forceCurrentTimeIndicator

WeekView component now supports forceCurrentTimeIndicator prop. When set, the current time indicator is displayed on the same day of week even when viewing a different week:

import { WeekView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <WeekView
      date="2030-06-10"
      events={events}
      withCurrentTimeIndicator
      forceCurrentTimeIndicator
    />
  );
}

New demo: MonthView events rendering

New MonthView demo shows how to use renderEvent to visually differentiate all-day and timed events. All-day events render as regular colored bars, while timed events display as a colored dot with the start time and title:

// Demo.tsx
import dayjs from 'dayjs';
import { Box, UnstyledButton } from '@mantine/core';
import { MonthView, ScheduleEventData } from '@mantine/schedule';

function isAllDayEvent(event: ScheduleEventData) {
  const start = dayjs(event.start);
  const end = dayjs(event.end);
  return start.isSame(start.startOf('day')) && end.isSame(end.startOf('day'));
}

const events: ScheduleEventData[] = [/* ...events */];

function Demo() {
  return (
    <MonthView
      date={new Date()}
      events={events}
      renderEvent={(event, props) => {
        if (isAllDayEvent(event)) {
          return <UnstyledButton {...props} />;
        }

        const { children, className, style, ...others } = props;
        return (
          <UnstyledButton
            {...others}
            style={{
              ...style,
              display: 'flex',
              alignItems: 'center',
              gap: 4,
              fontSize: 10,
              whiteSpace: 'nowrap',
              overflow: 'hidden',
              pointerEvents: 'all',
              cursor: 'pointer',
              paddingInline: 2,
            }}
          >
            <Box
              component="span"
              style={{
                width: 8,
                height: 8,
                borderRadius: '50%',
                backgroundColor: `var(--event-bg)`,
                flexShrink: 0,
              }}
            />
            <span style={{ width: 28, flexShrink: 0 }}>{dayjs(event.start).format('h:mm')}</span>
            <span style={{ overflow: 'hidden', textOverflow: 'ellipsis' }}>
              {event.title}
            </span>
          </UnstyledButton>
        );
      }}
    />
  );
}

Other changes

  • Tabs component now supports keepMountedMode prop that controls how inactive tab panels are hidden when keepMounted is true. Set keepMountedMode="display-none" to use display: none styles instead of the default Activity component.
  • useClickOutside hook now supports enabled parameter to dynamically enable/disable the listener. The hook also uses event.composedPath() in both ref and nodes branches for consistent Shadow DOM support and correctly ignores clicks on detached DOM nodes in the single-ref mode.
  • useCounter hook now supports step option to configure increment/decrement step size (default 1).
  • useDebouncedCallback hook now supports maxWait option to guarantee execution within a maximum time window during continuous calls, and isPending() method to check if a debounced call is waiting.
  • useDebouncedValue hook now returns a flush method to immediately apply the pending debounced value.
  • useScrollIntoView hook now supports onScrollCancel callback that fires when the scroll animation is interrupted by the user, and returns a scrolling boolean to indicate whether a scroll animation is in progress.

New @mantine/schedule package

New @mantine/schedule package provides a complete set of calendar scheduling components for React applications. It includes multiple view levels, drag-and-drop event management, and extensive customization options.

Schedule

Schedule is a unified container component that combines all views with built-in navigation and view switching. Drag events to reschedule them:

import { useState } from 'react';
import dayjs from 'dayjs';
import { Schedule, ScheduleEventData } from '@mantine/schedule';

const today = dayjs().format('YYYY-MM-DD');

Collapse horizontal orientation

Collapse component now supports horizontal orientation:

import { Button, Collapse, Stack, Typography } from '@mantine/core';
import { useDisclosure } from '@mantine/hooks';

function Demo() {
  const [expanded, handlers] = useDisclosure(false);

  return (
    <Stack h={240} align="flex-start">
      <Button onClick={handlers.toggle} w="fit-content">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <Collapse expanded={expanded} orientation="horizontal">
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md" w={200}>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua.
        </Typography>
      </Collapse>
    </Stack>
  );
}

use-collapse and use-horizontal-collapse hooks

New use-collapse hook is the hook version of Collapse component. It allows animation of height from 0 to auto and vice versa.

import { Button, Typography } from '@mantine/core';
import { useCollapse, useDisclosure } from '@mantine/hooks';

function Demo() {
  const [expanded, handlers] = useDisclosure(false);
  const getCollapseProps = useCollapse({ expanded });

  return (
    <>
      <Button onClick={handlers.toggle} mb="md">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <div {...getCollapseProps()}>
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md">
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation
          ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </Typography>
      </div>
    </>
  );
}

use-horizontal-collapse works the same way as use-collapse but animates width instead of height:

import { Button, Stack, Typography } from '@mantine/core';
import { useDisclosure, useHorizontalCollapse } from '@mantine/hooks';

function Demo() {
  const [expanded, handlers] = useDisclosure(false);
  const { getCollapseProps } = useHorizontalCollapse({ expanded });

  return (
    <Stack h={240}>
      <Button onClick={handlers.toggle} w="fit-content">
        {expanded ? 'Collapse' : 'Expand'}
      </Button>

      <div {...getCollapseProps({ style: { width: 200 } })}>
        <Typography bg="var(--mantine-color-blue-light)" p="xs" bdrs="md" w={200}>
          Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt
          ut labore et dolore magna aliqua.
        </Typography>
      </div>
    </Stack>
  );
}

use-floating-window hook

New use-floating-window hook allows creating floating draggable elements:

import { Button, CloseButton, Group, Paper, Portal, Text } from '@mantine/core';
import { useDisclosure, useFloatingWindow } from '@mantine/hooks';

function Demo() {
  const [visible, handlers] = useDisclosure();
  const floatingWindow = useFloatingWindow({
    constrainToViewport: true,
    constrainOffset: 20,
    excludeDragHandleSelector: 'button',
    initialPosition: { top: 300, left: 20 },
  });

  return (
    <>
      <Button onClick={handlers.toggle} variant="default">
        {visible ? 'Hide' : 'Show'} floating window
      </Button>

      {visible && (
        <Portal>
          <Paper
            w={280}
            p="md"
            withBorder
            pos="fixed"
            style={{ cursor: 'move', transition: 'box-shadow 70ms ease', zIndex: 400 }}
            shadow={floatingWindow.isDragging ? 'md' : undefined}
            ref={floatingWindow.ref}
          >
            <Group justify="space-between" mb="md">
              <Text>Usage demo</Text>
              <CloseButton onClick={handlers.close} />
            </Group>
            <Text fz="sm">This is a floating window. You can drag it around.</Text>
          </Paper>
        </Portal>
      )}
    </>
  );
}

FloatingWindow component

FloatingWindow provides component API for use-floating-window hook:

import { Button, CloseButton, FloatingWindow, Group, Text } from '@mantine/core';
import { useDisclosure } from '@mantine/hooks';

function Demo() {
  const [visible, handlers] = useDisclosure();

  return (
    <>
      <Button onClick={handlers.toggle} variant="default">
        {visible ? 'Hide' : 'Show'} floating window
      </Button>

      {visible && (
        <FloatingWindow
          w={280}
          p="md"
          withBorder
          excludeDragHandleSelector="button"
          initialPosition={{ top: 300, left: 20 }}
          style={{ cursor: 'move' }}
        >
          <Group justify="space-between" mb="md">
            <Text>Usage demo</Text>
            <CloseButton onClick={handlers.close} />
          </Group>
          <Text fz="sm">This is a floating window. You can drag it around.</Text>
        </FloatingWindow>
      )}
    </>
  );
}

OverflowList component

New OverflowList component displays list of items and collapses the overflowing items into a single element:

// OverflowListDemo.tsx
import { Badge, OverflowList } from '@mantine/core';
import { data } from './data';

function Demo() {
  return (
    <div style={{ resize: 'horizontal', overflow: 'auto', maxWidth: '100%' }}>
      <OverflowList
        data={data}
        gap={4}
        renderOverflow={(items) => <Badge>+{items.length} more</Badge>}
        renderItem={(item, index) => <Badge key={index}>{item}</Badge>}
      />
    </div>
  );
}

// data.ts
export const data = [
  'Apple',
  'Banana',
  'Cherry',
  'Date',
  'Elderberry',
  'Fig',
  'Grape',
  'Honeydew',
  'Indian Fig',

function Demo() {
  return (
    <Marquee gap="lg">
      <MantineLogo width={80} type="full" color="blue" />
      <MantineLogo width={80} type="full" color="cyan" />
      <MantineLogo width={80} type="full" color="teal" />

function Demo() {
  return (
    <Scroller>
      <Group gap="xs" wrap="nowrap">
        {Array.from({ length: 20 }).map((_, index) => (
          <Badge key={index} variant="light" size="lg">
            Badge {index + 1}

        style={{
          overflow: 'auto',
          cursor: scroller.isDragging ? 'grabbing' : 'grab',
        }}
      >
        <Group wrap="nowrap" gap="md">
          {Array.from({ length: 20 }).map((_, index) => (
            <Box

                display: 'flex',
                alignItems: 'center',
                justifyContent: 'center',
                color: 'white',
                fontWeight: 500,

Checkbox.Group and Switch.Group maxSelectedValues

Checkbox.Group and Switch.Group now support maxSelectedValues prop to limit the number of selected values. When the limit is reached, the remaining controls are disabled and cannot be selected.

import { Checkbox, Group } from '@mantine/core';

function Demo() {
  return (
    <Checkbox.Group defaultValue={['react']} maxSelectedValues={2}>
      <Group>
        <Checkbox value="react" label="React" />
        <Checkbox value="svelte" label="Svelte" />
        <Checkbox value="ng" label="Angular" />
        <Checkbox value="vue" label="Vue" />
      </Group>
    </Checkbox.Group>
  );
}

Inputs loading state

All Mantine input components based on Input component now support loading prop.

Set loading prop to display a loading indicator. By default, the loader is displayed on the right side of the input. You can change the position with the loadingPosition prop to 'left' or 'right'. This is useful for async operations like API calls, searches, or validations:

import { TextInput } from '@mantine/core';

function Demo() {
  return <TextInput placeholder="Your email" loading />;
}

renderPill in MultiSelect and TagsInput

MultiSelect and TagsInput components now support renderPill prop to customize pill rendering:

import { MultiSelect, Pill, Avatar } from '@mantine/core';

const users = [
  { value: 'Emily Johnson', label: 'Emily Johnson', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-7.png' },
  { value: 'Ava Rodriguez', label: 'Ava Rodriguez', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-8.png' },
  { value: 'Olivia Chen', label: 'Olivia Chen', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-4.png' },
  { value: 'Ethan Barnes', label: 'Ethan Barnes', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-1.png' },
  { value: 'Mason Taylor', label: 'Mason Taylor', image: 'https://raw.githubusercontent.com/mantinedev/mantine/master/.demo/avatars/avatar-2.png' },
];

const usersMap = new Map(users.map((user) => [user.value.toString(), user]));

function Demo() {
  return (
    <MultiSelect
      data={users}
      label="Candidates"
      placeholder="Select candidates"
      defaultValue={['Emily Johnson', 'Ava Rodriguez']}
      renderPill={({ option, onRemove }) => {
        const user = usersMap.get(option?.value.toString());
        return (
          <Pill withRemoveButton onRemove={onRemove}>
            <div style={{ display: 'flex', alignItems: 'center', gap: 8 }}>
              <Avatar src={user?.image} size={16} />
              {option?.label}
            </div>
          </Pill>
        );
      }}
    />
  );
}

Clear section mode

All clearable input components now support clearSectionMode prop that determines how the clear button and rightSection are rendered:

  • 'both' (default) – render both the clear button and rightSection
  • 'rightSection' – render only the user-supplied rightSection, ignore clear button
  • 'clear' – render only the clear button, ignore rightSection

This prop is supported by Select, Autocomplete, MultiSelect, TagsInput, FileInput, DateInput, DatePickerInput, MonthPickerInput, YearPickerInput, TimePicker, and DateTimePicker.

import { CaretDownIcon } from '@phosphor-icons/react';
import { Stack } from '@mantine/core';
import { DatePickerInput } from '@mantine/dates';

function Demo() {
  return (
    <Stack>
      <DatePickerInput
        label="clearSectionMode='both' (default)"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<CaretDownIcon size={16} />}
        clearSectionMode="both"
      />

      <DatePickerInput
        label="clearSectionMode='rightSection'"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<CaretDownIcon size={16} />}
        clearSectionMode="rightSection"
      />

      <DatePickerInput
        label="clearSectionMode='clear'"
        placeholder="Pick date"
        defaultValue={new Date()}
        clearable
        rightSection={<CaretDownIcon size={16} />}
        clearSectionMode="clear"
      />
    </Stack>
  );
}

use-form async validation

use-form validation rules can now be async – return a Promise that resolves to an error message or null. When all rules are synchronous, form.validate(), form.validateField() and form.isValid() return their results directly (not wrapped in a Promise). When any rule is async, these methods return promises instead. TypeScript infers the correct return type based on your validation rules, so you get precise types without manual annotations.

The form.validating property is true while any async validation is in progress, and form.isValidating(path) checks individual fields. The validating state is never set for forms with only synchronous rules.

Each rule receives an AbortSignal as the fourth argument. The signal is aborted when a newer validation supersedes the current one, which you can use to cancel in-flight HTTP requests.

import { Button, Group, Loader, TextInput } from '@mantine/core';
import { isEmail, useForm } from '@mantine/form';

// Simulates an async API call to check if the username is available
function checkUsernameAvailability(username: string, signal?: AbortSignal): Promise<string | null> {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => {
      const taken = ['admin', 'user', 'test', 'mantine'];
      resolve(taken.includes(username.toLowerCase()) ? 'Username is already taken' : null);
    }, 800);

    signal?.addEventListener('abort', () => {
      clearTimeout(timer);
      reject(new DOMException('Aborted', 'AbortError'));
    });
  });
}

function Demo() {
  const form = useForm({
    mode: 'uncontrolled',
    initialValues: { username: '', email: '' },
    validate: {
      username: async (value, _values, _path, signal) => {
        if (value.trim().length < 3) {
          return 'Username must be at least 3 characters';
        }
        return checkUsernameAvailability(value, signal);
      },
      email: isEmail('Invalid email'),
    },
  });

  return (
    <form onSubmit={form.onSubmit((values) => console.log(values))}>
      <TextInput
        withAsterisk
        label="Username"
        placeholder="Pick a username"
        key={form.key('username')}
        disabled={form.submitting}
        rightSection={form.validating ? <Loader size={16} /> : null}
        {...form.getInputProps('username')}
      />

      <TextInput
        withAsterisk
        mt="md"
        label="Email"
        placeholder="your@email.com"
        key={form.key('email')}
        disabled={form.submitting}
        {...form.getInputProps('email')}
      />

      <Group justify="flex-end" mt="md">
        <Button type="submit" loading={form.submitting}>
          Submit
        </Button>
      </Group>
    </form>
  );
}

When using async validation with validateInputOnChange, set validateDebounce to avoid firing an API call on every keystroke:

import { Button, Group, Loader, TextInput } from '@mantine/core';
import { useForm, isEmail } from '@mantine/form';

// Simulates an async API call to check if the username is available
function checkUsernameAvailability(username: string, signal?: AbortSignal): Promise<string | null> {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => {
      const taken = ['admin', 'user', 'test', 'mantine'];
      resolve(taken.includes(username.toLowerCase()) ? 'Username is already taken' : null);
    }, 800);

    signal?.addEventListener('abort', () => {
      clearTimeout(timer);
      reject(new DOMException('Aborted', 'AbortError'));
    });
  });
}

function Demo() {
  const form = useForm({
    mode: 'uncontrolled',
    initialValues: { username: '', email: '' },

    // Debounce async validation by 500ms – prevents firing
    // an API call on every keystroke
    validateDebounce: 500,
    validateInputOnChange: ['username'],

    validate: {
      username: async (value, _values, _path, signal) => {
        if (value.trim().length < 3) {
          return 'Username must be at least 3 characters';
        }
        return checkUsernameAvailability(value, signal);
      },
      email: isEmail('Invalid email'),
    },
  });

  return (
    <form onSubmit={form.onSubmit((values) => console.log(values))}>
      <TextInput
        withAsterisk
        label="Username"
        description="Try: admin, user, test, mantine"
        placeholder="Pick a username"
        key={form.key('username')}
        disabled={form.submitting}
        rightSection={form.isValidating('username') ? <Loader size={16} /> : null}
        {...form.getInputProps('username')}
      />

      <TextInput
        withAsterisk
        mt="md"
        label="Email"
        placeholder="your@email.com"
        key={form.key('email')}
        disabled={form.submitting}
        {...form.getInputProps('email')}
      />

      <Group justify="flex-end" mt="md">
        <Button type="submit" loading={form.submitting}>
          Submit
        </Button>
      </Group>
    </form>
  );
}

use-form TransformedValues type argument

use-form now supports passing second type argument TransformedValues to define the type of transformed values returned by form.getTransformedValues and form.onSubmit:

import { useForm } from '@mantine/form';

interface FormValues {
  name: string;
  locationId: string;
}

interface TransformedValues {
  name: string;
  locationId: number;
}

function Demo() {
  const form = useForm<FormValues, TransformedValues>({
    mode: 'uncontrolled',
    initialValues: {
      name: '',
      locationId: '2',
    },

    transformValues: (values) => ({
      ...values,
      locationId: Number(values.locationId),
    }),
  });
}

Generic components

SegmentedControl, Select, MultiSelect, Chip.Group, Switch.Group, Checkbox.Group and Radio.Group now support generic value type. You can pass primitive values (numbers, strings, booleans, bigint) as the type argument. The generic type is used for value, defaultValue, onChange and other props.

For example, generic type can now be used with SegmentedControl to specify string union:

import { SegmentedControl } from '@mantine/core';

function Demo() {
  return (
    <SegmentedControl<'orange' | 'grape' | 'apple'>
      data={[
        { value: 'orange', label: 'Orange' },
        { value: 'grape', label: 'Grape' },
        { value: 'apple', label: 'Apple' },
      ]}
    />
  );
}

Combobox virtualization

Combobox component now supports virtualization with the useVirtualizedCombobox hook. The hook does not depend on any specific virtualization library. The recommended option is @tanstack/react-virtual.

Example of implementation with useVirtualizedCombobox and @tanstack/react-virtual:

import { useState } from 'react';
import { useVirtualizer } from '@tanstack/react-virtual';
import { Combobox, Input, InputBase, ScrollArea, useVirtualizedCombobox } from '@mantine/core';

const ITEM_HEIGHT = 36;

const largeData = Array(10000)
  .fill(0)
  .map((_, index) => ({
    value: `value-${index}`,
    label: `Label ${index}`,
    id: `item-${index}`,
    disabled: false,
  }));

function Demo() {
  const [opened, setOpened] = useState(false);
  const [selectedOptionIndex, setSelectedOptionIndex] = useState(-1);
  const [activeOptionIndex, setActiveOptionIndex] = useState(-1);
  const [value, setValue] = useState('');
  const [scrollParent, setScrollParent] = useState<HTMLDivElement | null>(null);

  const virtualizer = useVirtualizer({
    count: largeData.length,
    getScrollElement: () => scrollParent,
    estimateSize: () => ITEM_HEIGHT,
    overscan: 5,
  });

  const combobox = useVirtualizedCombobox({
    opened,
    onOpenedChange: setOpened,
    onDropdownOpen: () => {
      if (activeOptionIndex !== -1) {
        setSelectedOptionIndex(activeOptionIndex);
        requestAnimationFrame(() => {
          virtualizer.scrollToIndex(activeOptionIndex, { align: 'auto' });
        });
      }
    },
    isOptionDisabled: (index) => largeData[index].disabled,
    totalOptionsCount: largeData.length,
    getOptionId: (index) => largeData[index].id,
    selectedOptionIndex,
    activeOptionIndex,
    setSelectedOptionIndex: (index) => {
      setSelectedOptionIndex(index);
      if (index !== -1) {
        virtualizer.scrollToIndex(index, { align: 'auto' });
      }
    },
    onSelectedOptionSubmit: onOptionSubmit,
  });

  function onOptionSubmit(index: number) {
    const option = largeData[index];
    setValue(option.value);
    setActiveOptionIndex(index);
    combobox.closeDropdown();
    combobox.resetSelectedOption();
  }

  return (
    <Combobox store={combobox} resetSelectionOnOptionHover={false} keepMounted>
      <Combobox.Target>
        <InputBase component="button" onClick={() => combobox.toggleDropdown()} pointer>
          {value || <Input.Placeholder>Pick a value</Input.Placeholder>}
        </InputBase>
      </Combobox.Target>
      <Combobox.Dropdown>
        <Combobox.Options>
          <ScrollArea.Autosize
            mah={220}
            type="scroll"
            scrollbarSize={4}
            viewportRef={setScrollParent}
            onMouseDown={(event) => event.preventDefault()}
          >
            <div style={{ height: virtualizer.getTotalSize(), position: 'relative' }}>
              {virtualizer.getVirtualItems().map((virtualItem) => {
                const item = largeData[virtualItem.index];
                return (
                  <Combobox.Option
                    value={item.value}
                    key={item.value}
                    active={virtualItem.index === activeOptionIndex}
                    selected={virtualItem.index === selectedOptionIndex}
                    onClick={() => onOptionSubmit(virtualItem.index)}
                    style={{
                      position: 'absolute',
                      top: 0,
                      left: 0,
                      width: '100%',
                      height: virtualItem.size,
                      transform: `translateY(${virtualItem.start}px)`,
                    }}
                  >
                    {item.label}
                  </Combobox.Option>
                );
              })}
            </div>
          </ScrollArea.Autosize>
        </Combobox.Options>
      </Combobox.Dropdown>
    </Combobox>
  );
}

You can find more virtualization examples on the Combobox examples page.

Highlight per-term colors

Highlight component now supports custom colors for individual highlight terms. You can provide an array of objects with text and color properties to assign different colors to different highlighted terms:

import { Highlight } from '@mantine/core';

function Demo() {
  return (
    <Highlight
      highlight={[
        { text: 'error', color: 'red' },
        { text: 'warning', color: 'yellow' },
        { text: 'success', color: 'green' },
      ]}
    >
      Error: Invalid input. Warning: Check this field. Success: All tests passed.
    </Highlight>
  );
}

Highlight whole-word matching

Highlight component now supports wholeWord prop to match only complete words. When enabled, 'the' will not match 'there' or 'theme':

import { Highlight, Stack, Text } from '@mantine/core';

function Demo() {
  return (
    <Stack gap="md">
      <div>
        <Text size="sm" fw={500} mb={5}>
          With whole word matching (wholeWord={'{'}true{'}'})
        </Text>
        <Highlight highlight="the" wholeWord>
          The theme is there
        </Highlight>
      </div>

      <div>
        <Text size="sm" fw={500} mb={5}>
          Without whole word matching (default)
        </Text>
        <Highlight highlight="the">The theme is there</Highlight>
      </div>
    </Stack>
  );
}

Pagination and use-pagination startValue

Pagination component and use-pagination hook now support startValue prop to define the starting page number. For example, with startValue={5} and total={15}, the pagination range will be from 5 to 15:

import { Text, Pagination } from '@mantine/core';

function Demo() {
  return (
    <>
      <Text mb="xs">Pages 5–15 (startValue=5, total=15)</Text>
      <Pagination total={15} startValue={5} defaultValue={5} />
    </>
  );
}

Grid improvements

Grid component no longer uses negative margins for spacing between columns. Instead, it now uses native CSS gap property, which means you no longer need to use overflow="hidden" to prevent content overflow caused by negative margins.

Slider vertical orientation

Slider and RangeSlider components now support vertical orientation:

import { RangeSlider, Slider } from '@mantine/core';

const marks = [
  { value: 20, label: '20%' },
  { value: 50, label: '50%' },
  { value: 80, label: '80%' },
];

function Demo() {
  return (
    <div style={{ display: 'flex', gap: 40 }}>
      <Slider orientation="vertical" defaultValue={45} marks={marks} />
      <RangeSlider orientation="vertical" defaultValue={[25, 65]} marks={marks} />
    </div>
  );
}

SimpleGrid improvements

SimpleGrid component now supports minColWidth prop to use CSS Grid auto-fill/auto-fit to automatically adjust the number of columns based on available space and minimum column width. When minColWidth is set, the cols prop is ignored. Use autoFlow prop to switch between auto-fill (default) and auto-fit behavior.

import { SimpleGrid } from '@mantine/core';

function Demo() {
  return (
    <SimpleGrid minColWidth="200px">
      <div>1</div>
      <div>2</div>
      <div>3</div>
      <div>4</div>
      <div>5</div>
    </SimpleGrid>
  );
}

SimpleGrid also now supports autoRows prop to control the size of implicitly created grid rows:

import { SimpleGrid } from '@mantine/core';

function Demo() {
  return (
    <SimpleGrid cols={3} autoRows="minmax(100px, auto)">
      <div>1</div>
      <div>2</div>
      <div>3</div>
      <div>4</div>
      <div>5</div>
    </SimpleGrid>
  );
}

Calendar fullWidth prop

Calendar, DatePicker, MonthPicker and YearPicker components now support fullWidth prop to make the calendar stretch to fill 100% of its parent container width:

import { Calendar } from '@mantine/dates';

function Demo() {
  return <Calendar fullWidth />;
}

Namespace types exports

Many Mantine components and hooks now provide namespace exports for related types. For example, use-disclosure hook types can now be accessed like this:

import { useDisclosure } from '@mantine/hooks';

const options: useDisclosure.Options = {
  onOpen: () => console.log('open'),
  onClose: () => console.log('close'),
};

function Demo() {
  const [opened, handlers] = useDisclosure(options);
}

Example of using namespace types with Button props type:

import { Button } from '@mantine/core';

const buttonProps: Button.Props = {
    variant: 'filled',
    size: 'md',
    disabled: false,
  };

function Demo() {
  return <Button {...buttonProps}>Click me</Button>;
}

Font weights

New fontWeights property was added to the theme object. It allows you to control font-weight values used across all components. The default values are:

  • regular400
  • medium600
  • bold700

Each value is mapped to a CSS variable: --mantine-font-weight-regular, --mantine-font-weight-medium, --mantine-font-weight-bold. All components that previously used hardcoded font-weight values now use these CSS variables.

For example, to revert the medium font weight from 600 back to 500 (the default in Mantine 8):

import { createTheme, MantineProvider } from '@mantine/core';

const theme = createTheme({
  fontWeights: {
    medium: '500',
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      {/* Your app here */}
    </MantineProvider>
  );
}

@mantine/mcp-server package

Mantine now includes @mantine/mcp-server package that exposes Mantine documentation over Model Context Protocol. It allows AI tools to query Mantine docs and props data through MCP tools instead of raw web scraping.

The server uses static data generated from Mantine documentation and serves:

  • item discovery with list_items
  • full documentation page retrieval with get_item_doc
  • normalized props metadata with get_item_props
  • keyword-based lookup with search_docs

This setup is useful in agent workflows where tools can call MCP functions directly to retrieve structured data and reduce prompt size.

Basic server configuration:

{
  "mcpServers": {
    "mantine": {
      "command": "npx",
      "args": ["-y", "@mantine/mcp-server"],
      "env": {
        "MANTINE_MCP_DATA_URL": "https://mantine.dev/mcp"
      }
    }
  }
}

For setup details, supported tools, and client-specific instructions, see Mantine with LLMs.

Mantine skills for Claude Code and Codex

Mantine skills for AI coding agents are documented in the Mantine with LLMs guide.

The guide includes:

  • available skills in mantinedev/skills
  • installation commands for each skill
  • separate usage instructions for Claude Code and Codex

New use-form validators

New isUrl and isOneOf validators were added to @mantine/form package:

  • isUrl – validates that the value is a valid URL. Supports custom protocols and localhost option.
  • isOneOf – validates that the value is included in the given list of allowed values.
import { isOneOf, isUrl, useForm } from '@mantine/form';

const form = useForm({
  mode: 'uncontrolled',
  initialValues: { website: '', role: '' },
  validate: {
    website: isUrl('Invalid URL'),
    role: isOneOf(['admin', 'user'], 'Invalid role'),
  },
});

Standard Schema support in use-form

@mantine/form now has built-in support for Standard Schema, a community specification implemented by Zod v4, Valibot, ArkType, and other schema libraries. Use schemaResolver to validate forms with any compliant library without installing a separate resolver package:

import { z } from 'zod/v4';
import { useForm, schemaResolver } from '@mantine/form';

const schema = z.object({
  name: z.string().min(2, { error: 'Name should have at least 2 letters' }),
  email: z.email({ error: 'Invalid email' }),
  age: z.number().min(18, { error: 'You must be at least 18 to create an account' }),
});

const form = useForm({
  mode: 'uncontrolled',
  initialValues: { name: '', email: '', age: 16 },
  validate: schemaResolver(schema, { sync: true }),
});

Pass { sync: true } when your schema is synchronous to get synchronous return types for form.validate(), form.validateField(), and form.isValid().

AppShell static mode

AppShell component now supports mode="static" which renders all AppShell elements as part of the normal document flow using CSS Grid instead of fixed positioning. Static mode supports layout="alt" to place navbar and aside at full height with header and footer adjusted between them. See AppShell examples for more details.

ScrollArea startScrollPosition

ScrollArea component now supports startScrollPosition prop to set the initial scroll position when the component mounts:

import { ScrollArea } from '@mantine/core';

function Demo() {
  return (
    <ScrollArea h={200} startScrollPosition={{ y: 250 }}>
      {/* ... content */}
    </ScrollArea>
  );
}

useEffectEvent migration in hooks

Five hooks — usePageLeave, useWindowEvent, useHotkeys, useClickOutside, and useCollapse — have been updated to use React 19's stable useEffectEvent. Previously these hooks captured stale closures or caused unnecessary event listener re-registrations when non-memoized callbacks were passed. With useEffectEvent, each hook registers a single stable listener that always calls the latest version of the provided callback, so wrapping callbacks in useCallback or useMemo is no longer required.

React 19 Activity for keepMounted

Transition, Collapse, Tabs.Panel, Stepper, and Tree now use React 19's Activity component when keepMounted is set. Activity preserves the state of hidden subtrees — form inputs, scroll positions, and any other component state survive while the content is not visible. Stepper and Tree gain a new keepMounted prop; all other components already had it.

import { useState } from 'react';
import { Stepper, TextInput } from '@mantine/core';

function Demo() {
  const [active, setActive] = useState(0);

  // TextInput values are preserved when navigating between steps
  return (
    <Stepper active={active} onStepClick={setActive} keepMounted>
      <Stepper.Step label="Step 1">
        <TextInput label="Value survives navigation" />
      </Stepper.Step>
      <Stepper.Step label="Step 2">
        <TextInput label="Value survives navigation" />
      </Stepper.Step>
    </Stepper>
  );
}

Documentation updates

  • New Custom components guide explaining how to create custom components with Mantine's styling system
  • New Controlled vs Uncontrolled guide explaining differences between controlled and uncontrolled components
  • HueSlider and AlphaSlider components now have their own documentation pages
  • Uncontrolled documentation and usage with FormData section was added to all inputs components
  • JsonInput documentation now includes custom serialization example with superjson library
  • Pagination documentation now includes URL synchronization examples for Next.js, react-router-dom and nuqs

Other changes

  • Notifications component now pauses auto close timer of all visible notifications when any notification is hovered (new default). Use pauseResetOnHover="notification" to keep the previous behavior of pausing only the hovered notification.
  • useHeadroom hook now returns { pinned: boolean; scrollProgress: number } object instead of a plain boolean. scrollProgress is a value between 0 (fully hidden) and 1 (fully visible) that can be used for scroll-linked reveal animations. A new scrollDistance option controls how many pixels of scrolling are required to fully reveal or hide the element (default: 100).
  • New useScrollDirection hook detects whether the user is currently scrolling up or down. It returns 'up', 'down', or 'unknown', handles resize events to avoid false direction changes, and always uses the latest state without stale closure issues.
  • Default theme.defaultRadius was changed from sm (4px) to md (8px)
  • light variant in all components now uses different colors values without transparency to improve contrast
  • mod prop now converts camelCase keys to kebab-case for data attributes in all components

  • @mantine/form getInputProps now supports type: 'radio' for individual radio inputs – returns checked/defaultChecked and passes through the radio option value
  • @mantine/form now supports async validation rules. form.validate(), form.validateField() and form.isValid() return results directly when all rules are synchronous and return promises only when async rules are present. New form.validating, form.isValidating(path), validateDebounce and resolveValidationError options were added.
  • createPolymorphicComponent function was renamed to shorter polymorphic for convenience
  • Mantine components now use theme-controlled fontWeights values. The default medium font weight was changed from 500 to 600 for better readability.

    • pis - padding-inline-start
    • pie - padding-inline-end
  • Tree component now supports controlled state via expandedState, selectedState and checkedState props.

  • Collapse, NavLink and Accordion.Panel now support keepMounted={false} prop to unmount collapsed content
  • Select and MultiSelect components now support primitive value types (numbers, booleans, strings) for data and value

  • TagsInput component now supports onMaxTags prop, which is called when the user attempts to add more tags than maxTags
  • Accordion component now supports ref prop
  • Text and Anchor components no longer accept color prop, use c style prop instead
  • PasswordInput component visibility toggle icon was updated
  • Popover and Tooltip components no longer accept positionDependencies prop, it is no longer required

  • FloatingIndicator component now supports onTransitionStart and onTransitionEnd callbacks
  • LoadingOverlay component now supports onEnter, onEntered, onExit and onExited callbacks
  • Grid component gutter prop was renamed to gap for consistency with other layout components. New rowGap and columnGap props allow separate control of row and column spacing. Grid.Col now supports align prop for per-column vertical alignment.
  • Indicator component now supports:
    • maxValue prop to display {maxValue}+ when the label exceeds the maximum value
    • showZero prop (default true) to control visibility of indicator with label 0
    • offset prop object with x and y properties for separate horizontal and vertical offsets
  • NumberInput component now supports:
    • onMinReached and onMaxReached callbacks
    • selectAllOnFocus prop to select all text when input is focused
    • bigint values for value, defaultValue, onChange, min, max, step and startValue (with string fallback for intermediate states)
  • RingProgress component now supports
    • sectionGap prop to add visual separation between sections in degrees
    • startAngle prop to control where the progress starts (0 = right, 90 = bottom, 180 = left, 270 = top)

  • use-fullscreen hook was split into two hooks: useFullscreenElement and useFullscreenDocument
  • use-media-query hook no longer includes fallback for old Safari versions (iOS 13 and earlier, released before 2019)
  • use-resize-observer now uses the new callback ref approach. The new approach makes hook usable with dynamic node changes. This change might be breaking, validate hook usage in your application.
  • use-mouse hook now uses the new callback ref approach to resolve the issue with stale refs. The previous hook functionality was split into two hooks: useMouse (for ref) and useMousePosition (for document).
  • use-mutation-observer hook now uses the new callback ref approach. The new approach makes hook usable with dynamic node changes. Additionally, a new useMutationObserverTarget hook was added for observing external target elements.
  • use-disclosure hook now supports new set handler
