Checkbox

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

{{"demo": "Checkboxes.js"}}

Label

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

{{"demo": "CheckboxLabels.js"}}

Size

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

{{"demo": "SizeCheckboxes.js"}}

Color

{{"demo": "ColorCheckboxes.js"}}

Icon

{{"demo": "IconCheckboxes.js"}}

Controlled

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

{{"demo": "ControlledCheckbox.js"}}

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.

You can change the indeterminate icon using the indeterminateIcon prop.

{{"demo": "IndeterminateCheckbox.js"}}

:::warning 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.

{{"demo": "CheckboxesGroup.js"}}

Label placement

You can change the placement of the label:

{{"demo": "FormControlLabelPosition.js"}}

Customization

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

{{"demo": "CustomizedCheckbox.js"}}

When to use

• Checkboxes vs. Radio Buttons
• Checkboxes vs. Switches

Accessibility

(WAI-ARIA: https://www.w3.org/WAI/ARIA/apg/patterns/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 (for example aria-label, aria-labelledby, title) via the slotProps.input prop.

<Checkbox
  value="checkedA"
  slotProps={{
    input: { 'aria-label': 'Checkbox A' },
  }}
/>
