Radio Button

<sl-radio-button> | SlRadioButton
Since 2.0 stable

Radios buttons allow the user to select a single option from a group using a button-like control.

Radio buttons are designed to be used with radio groups. When a radio button has focus, the arrow keys can be used to change the selected option just like standard radio controls.

Option 1 Option 2 Option 3 
<sl-radio-group label="Select an option" name="a" value="1">
  <sl-radio-button value="1">Option 1</sl-radio-button>
  <sl-radio-button value="2">Option 2</sl-radio-button>
  <sl-radio-button value="3">Option 3</sl-radio-button>
</sl-radio-group>

import SlRadioButton from '@shoelace-style/shoelace/dist/react/radio-button';
import SlRadioGroup from '@shoelace-style/shoelace/dist/react/radio-group';

const App = () => (
  <SlRadioGroup label="Select an option" name="a" value="1">
    <SlRadioButton value="1">Option 1</SlRadioButton>
    <SlRadioButton value="2">Option 2</SlRadioButton>
    <SlRadioButton value="3">Option 3</SlRadioButton>
  </SlRadioGroup>
);
