## Examples
### Getting the Selected Item
When dropdowns are used with [menus](/components/menu), you can listen for the `sl-select` event to determine which menu item was selected. The menu item element will be exposed in `event.detail.item`. You can set `value` props to make it easier to identify commands.
```html preview
<div class="dropdown-selection">
<sl-dropdown>
<sl-button slot="trigger" caret>Edit</sl-button>
<sl-menu>
<sl-menu-item value="cut">Cut</sl-menu-item>
<sl-menu-item value="copy">Copy</sl-menu-item>
<sl-menu-item value="paste">Paste</sl-menu-item>
</sl-menu>
</sl-dropdown>
</div>
<script>
const container = document.querySelector('.dropdown-selection');
const dropdown = container.querySelector('sl-dropdown');
dropdown.addEventListener('sl-select', event => {
const selectedItem = event.detail.item;
console.log(selectedItem.value);
});
</script>
```
Alternatively, you can listen for the `click` event on individual menu items. Note that, using this approach, disabled menu items will still emit a `click` event.

<sl-dropdown>
<sl-button slot="trigger" caret>Edit</sl-button>

copy.addEventListener('click', () => console.log('copy'));
paste.addEventListener('click', () => console.log('paste'));

### 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.
