Checkbox

Checkboxes allow the user to select one or more items from a set.

Checkboxes can be used to turn an option on or off.

If you have multiple options appearing in a list, you can preserve space by using checkboxes instead of on/off switches. If you have a single option, avoid using a checkbox and use an on/off switch instead.

Basic checkboxes

<Checkbox {...label} defaultChecked />
<Checkbox {...label} />
<Checkbox {...label} disabled />
<Checkbox {...label} disabled checked />

Label

You can provide a label to the Checkbox thanks to the FormControlLabel component.

<FormGroup>
  <FormControlLabel control={<Checkbox defaultChecked />} label="Label" />
  <FormControlLabel disabled control={<Checkbox />} label="Disabled" />
</FormGroup>

Size

Use the size prop or customize the font size of the svg icons to change the size of the checkboxes.

<Checkbox {...label} defaultChecked size="small" />
<Checkbox {...label} defaultChecked />
<Checkbox
  {...label}
  defaultChecked
  sx={{ '& .MuiSvgIcon-root': { fontSize: 28 } }}
/>

Color

<Checkbox {...label} defaultChecked />
<Checkbox {...label} defaultChecked color="secondary" />
<Checkbox {...label} defaultChecked color="success" />
<Checkbox {...label} defaultChecked color="default" />
<Checkbox
  {...label}
  defaultChecked
  sx={{
    color: pink[800],
    '&.Mui-checked': {
      color: pink[600],
    },
  }}
/>

Icon

<Checkbox {...label} icon={<FavoriteBorder />} checkedIcon={<Favorite />} />
<Checkbox
  {...label}
  icon={<BookmarkBorderIcon />}
  checkedIcon={<BookmarkIcon />}
/>

Controlled

You can control the checkbox with the checked and onChange props:

<Checkbox
  checked={checked}
  onChange={handleChange}
  inputProps={{ 'aria-label': 'controlled' }}
/>

Indeterminate

A checkbox input can only have two states in a form: checked or unchecked. It either submits its value or doesn't. Visually, there are three states a checkbox can be in: checked, unchecked, or indeterminate.

<FormControlLabel
  label="Parent"
  control={
    <Checkbox
      checked={checked[0] && checked[1]}
      indeterminate={checked[0] !== checked[1]}
      onChange={handleChange1}
    />
  }
/>
{children}

⚠️ When indeterminate is set, the value of the checked prop only impacts the form submitted values. It has no accessibility or UX implications.

FormGroup

FormGroup is a helpful wrapper used to group selection control components.

Here is an example of customizing the component. You can learn more about this in the overrides documentation page.

<BpCheckbox />
<BpCheckbox defaultChecked />

When to use

Accessibility

(WAI-ARIA: https://www.w3.org/TR/wai-aria-practices/#checkbox)

  • All form controls should have labels, and this includes radio buttons, checkboxes, and switches. In most cases, this is done by using the <label> element (FormControlLabel).
  • When a label can't be used, it's necessary to add an attribute directly to the input component. In this case, you can apply the additional attribute (e.g. aria-label, aria-labelledby, title) via the inputProps prop.
<Checkbox
  value="checkedA"
  inputProps={{
    'aria-label': 'Checkbox A',
  }}
/>
