Radio

Radio.

When To Use#

  • Used to select a single state from multiple options.

  • The difference from Select is that Radio is visible to the user and can facilitate the comparison of choice, which means there shouldn't be too many of them.

Examples

Passing the name property to all input[type="radio"] that are in the same Radio.Group. It is usually used to let the browser see your Radio.Group as a real "group" and keep the default behavior. For example, using left/right keyboard arrow to change your selection that in the same Radio.Group.

import { Radio } from 'antd';

function App() {
