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.

<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>
