#### 单文件递归菜单
 | 
						|
使用单文件方式递归生成菜单。
 | 
						|
因组件内部会动态更改`a-sub-menu`的属性,如果拆分成单文件,无法将属性挂载到`a-sub-menu`上,你需要自行声明属性并挂载。为了实现方便,避免了属性的声明,本示例将其声明为函数式组件,并将所有属性挂载到`a-sub-menu`上。

#### Single file recursive menu
 | 
						|
Use the single file method to recursively generate menus.
 | 
						|
The properties of `a-sub-menu` are dynamically changed inside the component. If you split the file into a single file and you cannot mount the `props` to `a-sub-menu`, you need to declare the `props` and mount it yourself. For the sake of convenience, the declaration of the `props` is avoided. This example declares it as a functional component and mounts all properties to `a-sub-menu`.
