## 何时使用

当页面上的操作命令过多时，用此组件可以收纳操作元素。点击或移入触点，会出现一个下拉菜单。可在列表中进行选择，并执行相应的命令。

## API

属性如下

| 参数 | 说明 | 类型 | 默认值 |
| --- | --- | --- | --- |
| disabled | 菜单是否禁用 | boolean | - |
| getPopupContainer | 菜单渲染父节点。默认渲染到 body 上，如果你遇到菜单滚动定位问题，试试修改为滚动的区域，并相对其定位。[示例](https://codepen.io/afc163/pen/zEjNOy?editors=0010) | Function(triggerNode) | `() => document.body` |
| overlay | 菜单 | [Menu](/components/menu) \| () => Menu | - |
| overlayClassName | 下拉根元素的类名称 | string | - |
| overlayStyle | 下拉根元素的样式 | object | - |
| placement | 菜单弹出位置：`bottomLeft` `bottomCenter` `bottomRight` `topLeft` `topCenter` `topRight` | String | `bottomLeft` |
| trigger | 触发下拉的行为, 移动端不支持 hover | Array&lt;`click`\|`hover`\|`contextMenu`> | `['hover']` |
| visible | 菜单是否显示 | boolean | - |
| onVisibleChange | 菜单显示状态改变时调用，参数为 visible | Function(visible) | - |

`overlay` 菜单使用 [Menu](/components/menu/)，还包括菜单项 `Menu.Item`，分割线 `Menu.Divider`。

> 注意： Menu.Item 必须设置唯一的 key 属性。
>
> Dropdown 下的 Menu 默认不可选中。如果需要菜单可选中，可以指定 `<Menu selectable>`.
