A dropdown list.
## When To Use
If there are too many operations to display, you can wrap them in a `Dropdown`. By clicking/hovering on the trigger, a dropdown menu should appear, which allows you to choose one option and execute relevant actions.
## API
### Dropdown

| trigger | the trigger mode which executes the drop-down action | Array<`click`\|`hover`> | [`hover`] |
| overlay | the dropdown menu | [Menu](/components/menu) | - |
| getPopupContainer | to set the container of the dropdown menu. The default is to create a `div` element in `body`, you can reset it to the scrolling area and make a relative reposition. [example](https://codepen.io/afc163/pen/zEjNOy?editors=0010) | Function(triggerNode) | () => document.body |
