Radio

Use radios when a user needs to select one option from a list

Alpha
Not reviewed for accessibility

Use FormControl to render a standard radio input field. This component is only meant to be used in the case that you're building a custom radio that is not yet supported by Primer (For example: the color mode selection in Appearance settings)

If you do use this component to build a custom radio, it should always be accompanied by a corresponding <label> to improve support for assistive technologies.

<>
  <Radio value="one" name="radio-group-name" />
  <Radio value="two" name="radio-group-name" />
  <Radio disabled value="three" name="radio-group-name" />
</>

<>
  <Radio value="one" name="radio-group-name" />
  <Radio value="two" name="radio-group-name" />
  <Radio disabled value="three" name="radio-group-name" />
</>

Please use a Checkbox if the user needs to select more than one option in a list

Use the name prop to group together related Radio components in a list.

If you're not building something custom, you should use the RadioGroup component to render a group of radio inputs.
