Radio Buttons

Radio buttons allow the user to select one option from a set. Use radio buttons for exclusive selection if you think that the user needs to see all available options side-by-side.

• Module @rmwc/radio
• Import styles:
  • Using CSS Loader
    • import '@rmwc/radio/styles';
  • Or include stylesheets
    • '@material/radio/dist/mdc.radio.css'
    • '@material/form-field/dist/mdc.form-field.css'
    • '@material/ripple/dist/mdc.ripple.css'
• MDC Docs: https://material.io/develop/web/components/input-controls/radio-buttons/

Controlled Usage

function Example() {
  const [value, setValue] = React.useState('cookies');

  return (
    <>
      <Radio
        value="cookies"
        checked={value === 'cookies'}
        onChange={(evt) => setValue(String(evt.currentTarget.value))}
      >
        Cookies
      </Radio>

      <Radio
        value="pizza"
        checked={value === 'pizza'}
        onChange={(evt) => setValue(String(evt.currentTarget.value))}
      >
        Pizza
      </Radio>

      <Radio
        value="icecream"
        checked={value === 'icecream'}
        onChange={(evt) => setValue(String(evt.currentTarget.value))}
      >
        Icecream
      </Radio>
    </>
  );
}

Uncontrolled Usage

You can use Radio Buttons and receive change events without having to manually set the checked prop. Just give the Radio components the same name. This example also shows using the label prop instead of setting the label as a child.

<>
  <Radio
    label="Cookies"
    value="cookies"
    name="myRadioGroup"
    onChange={(evt) => console.log(evt.currentTarget.value)}
  />

  <Radio
    label="Pizza"
    value="pizza"
    name="myRadioGroup"
    onChange={(evt) => console.log(evt.currentTarget.value)}
  />

  <Radio
    label="Icecream"
    value="icecream"
    name="myRadioGroup"
    onChange={(evt) => console.log(evt.currentTarget.value)}
  />
</>
