可以为 RadioGroup 配置 `name` 参数，为组合内的 input 元素赋予相同的 `name` 属性，使浏览器把 RadioGroup 下的 Radio 真正看作是一组（例如可以通过方向键始终**在同一组内**更改选项）。

 en-US

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

```jsx
import { Radio } from 'parkball';

const RadioGroup = Radio.Group;

function App() {
  return (
    <RadioGroup name="radiogroup" defaultValue={1}>
      <Radio value={1}>A</Radio>
      <Radio value={2}>B</Radio>
      <Radio value={3}>C</Radio>
      <Radio value={4}>D</Radio>
    </RadioGroup>
  );
}

ReactDOM.render(<App />, mountNode);
```
