Styles API attributes

You now can pass attributes to inner elements of all components that support Styles API with attributes prop. For example, it can be used to add data attributes for testing purposes:

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

function Demo() {
  return (
    <Button
      attributes={{
        root: { 'data-test-id': 'root' },
        label: { 'data-test-id': 'label' },
        inner: { 'data-test-id': 'inner' },
      }}
    >
      Button
    </Button>
  );
}

Container grid strategy

Container now supports strategy="grid" prop which enables more features.

Differences from the default strategy="block":

Uses display: grid instead of display: block
Does not include default inline padding
Does not set max-width on the root element (uses grid template columns instead)

Features supported by strategy="grid":

Everything that is supported by strategy="block"
Children with data-breakout attribute take the entire width of the container's parent element
Children with data-container inside data-breakout have the same width as the main grid column

Example of using breakout feature:

Main content

Breakout

Container inside breakout

import { Box, Container } from '@mantine/core';

function Demo() {
  return (
    <Container strategy="grid" size={500}>
      <Box bg="var(--mantine-color-indigo-light)" h={50}>
        Main content
      </Box>

      <Box data-breakout bg="var(--mantine-color-indigo-light)" mt="xs">
        <div>Breakout</div>

        <Box data-container bg="indigo" c="white" h={50}>
          <div>Container inside breakout</div>
        </Box>
      </Box>
    </Container>
  );
}

New Tooltip target prop is an alternative to children. It accepts a string (selector), an HTML element or a ref object with HTML element. Use target prop when you do not render tooltip target as JSX element.

Example of using target prop with a string selector:

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

function Demo() {
  return (
    <>
      <Tooltip target="#hover-me" label="Tooltip over button" />
      <Button id="hover-me">Hover me to see tooltip</Button>
    </>
  );
}

HoverCard.Group

HoverCard now supports delay synchronization between multiple instances using HoverCard.Group component:

import { HoverCard, Button, Text, Group } from '@mantine/core';

function Demo() {
  return (
    <HoverCard.Group openDelay={500} closeDelay={100}>
      <Group justify="center">
        <HoverCard shadow="md">
          <HoverCard.Target>
            <Button>First</Button>
          </HoverCard.Target>
          <HoverCard.Dropdown>
            <Text size="sm">First hover card content</Text>
          </HoverCard.Dropdown>
        </HoverCard>

        <HoverCard shadow="md">
          <HoverCard.Target>
            <Button>Second</Button>
          </HoverCard.Target>
          <HoverCard.Dropdown>
            <Text size="sm">Second hover card content</Text>
          </HoverCard.Dropdown>
        </HoverCard>

        <HoverCard shadow="md">
          <HoverCard.Target>
            <Button>Third</Button>
          </HoverCard.Target>
          <HoverCard.Dropdown>
            <Text size="sm">Third hover card content</Text>
          </HoverCard.Dropdown>
        </HoverCard>
      </Group>
    </HoverCard.Group>
  );
}

use-selection hook

New use-selection hook:

Element position	Element name	Symbol	Atomic mass
6	Carbon	C	12.011
7	Nitrogen	N	14.007
39	Yttrium	Y	88.906
56	Barium	Ba	137.33
58	Cerium	Ce	140.12

import { Checkbox, Table } from '@mantine/core';
import { useSelection } from '@mantine/hooks';

const elements = [
  { position: 6, mass: 12.011, symbol: 'C', name: 'Carbon' },
  { position: 7, mass: 14.007, symbol: 'N', name: 'Nitrogen' },
  { position: 39, mass: 88.906, symbol: 'Y', name: 'Yttrium' },
  { position: 56, mass: 137.33, symbol: 'Ba', name: 'Barium' },
  { position: 58, mass: 140.12, symbol: 'Ce', name: 'Cerium' },
];

function Demo() {
  const positions = useMemo(() => elements.map((element) => element.position), [elements]);

  const [selection, handlers] = useSelection({
    data: positions,
    defaultSelection: [39, 56],
  });

  const rows = elements.map((element) => {
    const isSelected = selection.includes(element.position);
    return (
      <Table.Tr key={element.name} bg={isSelected ? 'var(--mantine-color-blue-light)' : undefined}>
        <Table.Td>
          <Checkbox
            aria-label="Select row"
            checked={isSelected}
            onChange={(event) => {
              if (event.target.checked) {
                handlers.select(element.position);
              } else {
                handlers.deselect(element.position);
              }
            }}
          />
        </Table.Td>
        <Table.Td>{element.position}</Table.Td>
        <Table.Td>{element.name}</Table.Td>
        <Table.Td>{element.symbol}</Table.Td>
        <Table.Td>{element.mass}</Table.Td>
      </Table.Tr>
    );
  });

  return (
    <Table>
      <Table.Thead>
        <Table.Tr>
          <Table.Th>
            <Checkbox
              aria-label="Select deselect all rows"
              indeterminate={handlers.isSomeSelected()}
              checked={handlers.isAllSelected()}
              onChange={() => {
                if (handlers.isAllSelected()) {
                  handlers.resetSelection();
                } else {
                  handlers.setSelection(elements.map((el) => el.position));
                }
              }}
            />
          </Table.Th>
          <Table.Th>Element position</Table.Th>
          <Table.Th>Element name</Table.Th>
          <Table.Th>Symbol</Table.Th>
          <Table.Th>Atomic mass</Table.Th>
        </Table.Tr>
      </Table.Thead>
      <Table.Tbody>{rows}</Table.Tbody>
    </Table>
  );
}

autoSelectOnBlur prop

Select and Autocomplete components now support autoSelectOnBlur prop. Use it to automatically select the highlighted option when the input loses focus. To see this feature in action: select an option with up/down arrows, then click outside the input:

Your favorite library

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

function Demo() {
  return (
    <Select
      label="Your favorite library"
      placeholder="Pick value"
      autoSelectOnBlur
      searchable
      data={['React', 'Angular', 'Vue', 'Svelte']}
    />
  );
}

Source edit mode in RichTextEditor

RichTextEditor now supports source edit mode:

import { useEditor } from '@tiptap/react';
import StarterKit from '@tiptap/starter-kit';
import { RichTextEditor } from '@mantine/tiptap';
import { useState } from 'react';

function Demo() {
  const [isSourceCodeModeActive, onSourceCodeTextSwitch] = useState(false)

  const editor = useEditor({
    extensions: [StarterKit],
    content: '<p>Source code control example</p><p>New line with <strong>bold text</strong></p><p>New line with <em>italic</em> <em>text</em></p>',
  });

  return (
    <RichTextEditor editor={editor} onSourceCodeTextSwitch={onSourceCodeTextSwitch}>
      <RichTextEditor.Toolbar>
        <RichTextEditor.ControlsGroup>
          <RichTextEditor.SourceCode icon={BoldIcon} />
        </RichTextEditor.ControlsGroup>
        {!isSourceCodeModeActive && (
          <RichTextEditor.ControlsGroup>
            <RichTextEditor.Blockquote />
            <RichTextEditor.Bold />
            <RichTextEditor.Italic />
            <RichTextEditor.Underline />
            <RichTextEditor.Strikethrough />
            <RichTextEditor.ClearFormatting />
            <RichTextEditor.Highlight />
