 #### 单选组合 - 配合 name 使用
-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）。

-#### RadioGroup with name
-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.
