# Dropdown

|
|
|
||
|
|
Dropdowns expose additional content that "drops down" in a panel.
|
||
|
|
|
||
|
|
Dropdowns consist of a trigger and a panel. By default, activating the trigger will expose the panel and interacting outside of the panel will close it.
|
||
|
|
|
||
|
|
Dropdowns are designed to work well with [menus](/components/menu.md) to provide a list of options the user can select from. However, dropdowns can also be used in lower-level applications (e.g. [color picker](/components/color-picker.md) and [select](/components/select.md)). The API gives you complete control over showing, hiding, and positioning the panel.

## Examples
|
||
|
|
|
||
|
|
### Placement
|
||
|
|
|
||
|
|
The preferred placement of the dropdown can be set with the `placement` attribute. Note that the actual position may vary to ensure the panel remains in the viewport.
|
||
|
|
|
||
|
|
```html preview
|
||
|
|
<sl-dropdown placement="top-start">
|
||
|
|
<sl-button slot="trigger" caret>Edit</sl-button>
|
||
|
|
<sl-menu>
|
||
|
|
<sl-menu-item>Cut</sl-menu-item>
|
||
|
|
<sl-menu-item>Copy</sl-menu-item>
|
||
|
|
<sl-menu-item>Paste</sl-menu-item>
|
||
|
|
<sl-menu-divider></sl-menu-divider>
|
||
|
|
<sl-menu-item>Find</sl-menu-item>
|
||
|
|
<sl-menu-item>Replace</sl-menu-item>
|
||
|
|
</sl-menu>
|
||
|
|
</sl-dropdown>
|
||
|
|
```
|
||
|
|
|
||
|
|
### Distance
|
||
|
|
|
||
|
|
The distance from the panel to the trigger can be customized using the `distance` attribute. This value is specified in pixels.
|
||
|
|
|
||
|
|
```html preview
|
||
|
|
<sl-dropdown distance="30">
|
||
|
|
<sl-button slot="trigger" caret>Edit</sl-button>
|
||
|
|
<sl-menu>
|
||
|
|
<sl-menu-item>Cut</sl-menu-item>
|
||
|
|
<sl-menu-item>Copy</sl-menu-item>
|
||
|
|
<sl-menu-item>Paste</sl-menu-item>
|
||
|
|
<sl-menu-divider></sl-menu-divider>
|
||
|
|
<sl-menu-item>Find</sl-menu-item>
|
||
|
|

|
||
|
|
</sl-menu>
|
||
|
|
</sl-dropdown>
|
||
|
|
```
|
||
|
|
|
||
|
|
### Skidding
|
||
|
|
|
||
|
|
The offset of the panel along the trigger can be customized using the `skidding` attribute. This value is specified in pixels.
|
||
|
|
|
||
|
|
```html preview
|
||
|
|
<sl-dropdown skidding="30">
|
||
|
|
<sl-button slot="trigger" caret>Edit</sl-button>
