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.
