Usage

Label position

Size
import { Checkbox } from '@mantine/core';

function Demo() {
  return (
    <Checkbox
      defaultChecked
      label="I agree to sell my privacy"
    />
  );
}

Controlled

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

function Demo() {
  const [checked, setChecked] = useState(false);
  return (
    <Checkbox
      checked={checked}
      onChange={(event) => setChecked(event.currentTarget.checked)}
    />
  );
}

States

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

function Demo() {
  return (
    <Stack>
      <Checkbox checked={false} onChange={() => {}} label="Default checkbox" />
      <Checkbox checked={false} onChange={() => {}} indeterminate label="Indeterminate checkbox" />
      <Checkbox checked onChange={() => {}} label="Checked checkbox" />
      <Checkbox checked variant="outline" onChange={() => {}} label="Outline checked checkbox" />
      <Checkbox
        variant="outline"
        onChange={() => {}}
        indeterminate
        label="Outline indeterminate checkbox"
      />
      <Checkbox disabled label="Disabled checkbox" />
      <Checkbox disabled checked onChange={() => {}} label="Disabled checked checkbox" />
      <Checkbox disabled indeterminate label="Disabled indeterminate checkbox" />
    </Stack>
  );
}

Change icons

import { Checkbox, CheckboxProps } from '@mantine/core';
import { IconBiohazard, IconRadioactive } from '@tabler/icons-react';

const CheckboxIcon: CheckboxProps['icon'] = ({ indeterminate, ...others }) =>
  indeterminate ? <IconRadioactive {...others} /> : <IconBiohazard {...others} />;

function Demo() {
  return (
    <>
      <Checkbox icon={CheckboxIcon} label="Custom icon" defaultChecked />
      <Checkbox icon={CheckboxIcon} label="Custom icon: indeterminate" indeterminate mt="sm" />
    </>
  );
}

Change icon color

Use iconColor prop to change icon color. You can reference colors from theme.colors or use any valid CSS color:

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

function Demo() {
  return (
    <Checkbox
      defaultChecked
      color="lime.4"
      iconColor="dark.8"
      size="md"
      label="Bright lime checkbox"
    />
  );
}

Indeterminate state

Checkbox supports indeterminate state. When indeterminate prop is set, checked prop is ignored (checkbox always has checked styles):

import { useListState, randomId } from '@mantine/hooks';
import { Checkbox } from '@mantine/core';

const initialValues = [
  { label: 'Receive email notifications', checked: false, key: randomId() },
  { label: 'Receive sms notifications', checked: false, key: randomId() },
  { label: 'Receive push notifications', checked: false, key: randomId() },
];

export function IndeterminateCheckbox() {
  const [values, handlers] = useListState(initialValues);

  const allChecked = values.every((value) => value.checked);
  const indeterminate = values.some((value) => value.checked) && !allChecked;

  const items = values.map((value, index) => (
    <Checkbox
      mt="xs"
      ml={33}
      label={value.label}
      key={value.key}
      checked={value.checked}
      onChange={(event) => handlers.setItemProp(index, 'checked', event.currentTarget.checked)}
    />
  ));

  return (
    <>
      <Checkbox
        checked={allChecked}
        indeterminate={indeterminate}
        label="Receive all notifications"
        onChange={() =>
          handlers.setState((current) =>
            current.map((value) => ({ ...value, checked: !allChecked }))
          )
        }
      />
      {items}
    </>
  );
}

Label with link

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

function Demo() {
  return (
    <Checkbox
      label={
        <>
          I accept{' '}
          <Anchor href="https://mantine.dev" target="_blank" inherit>
            terms and conditions
          </Anchor>
        </>
      }
    />
  );
}

Checkbox with tooltip

You can change target element to which tooltip is attached with refProp:

  • If refProp is not set, the tooltip is attached to the checkbox input
  • If refProp="rootRef" is set, the tooltip is attached to the root element (contains label, input and other elements)
import { Tooltip, Checkbox } from '@mantine/core';

function Demo() {
  return (
    <>
      <Tooltip label="Checkbox with tooltip">
        <Checkbox label="Tooltip on checkbox only" />
      </Tooltip>

      <Tooltip label="Checkbox with tooltip" refProp="rootRef">
        <Checkbox label="Tooltip the entire element" mt="md" />
      </Tooltip>
    </>
  );
}

Pointer cursor

By default, checkbox input and label have cursor: default (same as native input[type="checkbox"]). To change cursor to pointer, set cursorType on theme:

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

const theme = createTheme({
  cursorType: 'pointer',
});

function Demo() {
  return (
    <>
      <Checkbox label="Default cursor" />

      <MantineProvider theme={theme}>
        <Checkbox label="Pointer cursor" mt="md" />
      </MantineProvider>
    </>
  );
}

Add custom sizes

You can add any number of custom sizes with data-size attribute:

import { MantineProvider, Checkbox, createTheme } from '@mantine/core';
import classes from './Demo.module.css';

const theme = createTheme({
  components: {
    Checkbox: Checkbox.extend({ classNames: classes }),
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <Checkbox size="xxs" label="Extra small checkbox" />
      <Checkbox size="xxl" label="Extra large checkbox" mt="md" />
    </MantineProvider>
  );
}

Add props to the root element

All props passed to the component are forwarded to the input element. If you need to add props to the root element, use wrapperProps. In the following example:

  • data-testid="wrapper" is added to the root element
  • data-testid="input" is added to the input element
import { Checkbox } from '@mantine/core';

function Demo() {
  return <Checkbox wrapperProps={{ 'data-testid': 'wrapper' }} data-testid="input" />;
}

Checkbox.Group

Select your favorite frameworks/libraries

This is anonymous

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

function Demo() {
  return (
    <Checkbox.Group
      defaultValue={['react']}
      label="Select your favorite frameworks/libraries"
      description="This is anonymous"
      withAsterisk
    >
      <Group mt="xs">
        <Checkbox value="react" label="React" />
        <Checkbox value="svelte" label="Svelte" />
        <Checkbox value="ng" label="Angular" />
        <Checkbox value="vue" label="Vue" />
      </Group>
    </Checkbox.Group>
  );
}

Controlled Checkbox.Group

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

function Demo() {
  const [value, setValue] = useState<string[]>([]);

  return (
    <Checkbox.Group value={value} onChange={setValue}>
      <Checkbox value="react" label="React" />
      <Checkbox value="svelte" label="Svelte" />
    </Checkbox.Group>
  );
}

Get element ref

import { useRef } from 'react';
import { Checkbox } from '@mantine/core';

function Demo() {
  const ref = useRef<HTMLInputElement>(null);
  return <Checkbox ref={ref} />;
}

Styles API

Checkbox supports Styles API, you can add styles to any inner element of the component withclassNames prop. Follow Styles API documentation to learn more.

Component Styles API

Hover over selectors to highlight corresponding elements

/*
 * Hover over selectors to apply outline styles

 */

Example: Table with row selection

Element positionElement nameSymbolAtomic mass
6CarbonC12.011
7NitrogenN14.007
39YttriumY88.906
56BariumBa137.33
58CeriumCe140.12
import { useState } from 'react';
import { Table, Checkbox } from '@mantine/core';

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 [selectedRows, setSelectedRows] = useState<number[]>([]);

  const rows = elements.map((element) => (
    <Table.Tr
      key={element.name}
      bg={selectedRows.includes(element.position) ? 'var(--mantine-color-blue-light)' : undefined}
    >
      <Table.Td>
        <Checkbox
          aria-label="Select row"
          checked={selectedRows.includes(element.position)}
          onChange={(event) =>
            setSelectedRows(
              event.currentTarget.checked
                ? [...selectedRows, element.position]
                : selectedRows.filter((position) => position !== 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 />
          <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>
  );
}

Example: Checkbox card

import { useState } from 'react';
import { Checkbox, UnstyledButton, Text } from '@mantine/core';
import classes from './Demo.module.css';

function Demo() {
  const [checked, setChecked] = useState(false);

  return (
    <div className={classes.root}>
      <Checkbox
        classNames={{ root: classes.checkboxWrapper, input: classes.checkbox }}
        checked={checked}
        onChange={(event) => setChecked(event.currentTarget.checked)}
        tabIndex={-1}
        size="md"
        aria-label="Checkbox example"
      />

      <UnstyledButton
        className={classes.control}
        data-checked={checked || undefined}
        onClick={() => setChecked((c) => !c)}
      >
        <Text className={classes.label}>@mantine/core</Text>
        <Text className={classes.description}>
          Core components library: inputs, buttons, overlays, etc.
        </Text>
      </UnstyledButton>
    </div>
  );
}

Example: Customize with Styles API

import { useState } from 'react';
import { Checkbox } from '@mantine/core';
import classes from './Demo.module.css';

function Demo() {
  const [checked, setChecked] = useState(false);

  return (
    <Checkbox
      classNames={classes}
      label="Checkbox button"
      checked={checked}
      onChange={(event) => setChecked(event.currentTarget.checked)}
      wrapperProps={{
        onClick: () => setChecked((c) => !c),
      }}
    />
  );
}

Accessibility

Set aria-label or label prop to make the checkbox accessible:

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

// Not ok, input is not labeled
function Bad() {
  return <Checkbox />;
}

// Ok, input is labelled by aria-label
function GoodAriaLabel() {
  return <Checkbox aria-label="My checkbox" />;
}

// Ok, input is labelled by label element
function GoodLabel() {
  return <Checkbox label="My checkbox" />;
}
