## 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。
|
||
|
||
- 用于收罗一组命令操作。
|
||
- Select 用于选择，而 Dropdown 是命令集合。

## FAQ
|
||
|
||
### Dropdown 在水平方向超出屏幕时会被挤压该怎么办？
|
||
|
||
你可以通过 `width: max-content` 来解决这个问题，参考 [#43025](https://github.com/ant-design/ant-design/issues/43025#issuecomment-1594394135)。
