}

States

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


function Demo() {
  return (
    <>
      <Checkbox />
      <Checkbox indeterminate />
      <Checkbox checked indeterminate />
      <Checkbox checked />
      <Checkbox disabled />
      <Checkbox disabled checked />
      <Checkbox disabled indeterminate />
    </>
  );
}

Replace icon

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


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


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

Sizes

Checkbox has 5 predefined sizes: xs, sm, md, lg, xl. Size defines label font-size, input width and height:

<Checkbox size="xl" /> // -> predefined xl size

Indeterminate state

Checkbox supports indeterminate state. When indeterminate prop is true, checked prop is ignored:

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)} />
  );
}

Label with link

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


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

Checkbox.Group

Select your favorite frameworks/libraries
This is anonymous
import { Checkbox } 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 input ref

You can get input ref by setting ref prop:

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


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

Accessibility

Provide aria-label in case you use checkbox without label for screen reader support:

<Checkbox /> // -> not ok, input is not labeled
<Checkbox label="My checkbox" /> // -> ok, input and label is connected
<Checkbox aria-label="My checkbox" /> // -> ok, label is not visible but will be announced by screen reader
