Menu (Dropdown)

Menus offer an easy way to build custom, accessible dropdown components with robust support for keyboard navigation.

Open in separate tab

Example

<script lang="ts">
  import { createMenu } from 'svelte-headlessui'
  import Transition from 'svelte-transition'
  import Archive from './Archive.svelte'
  import ChevronDown from './ChevronDown.svelte'
  import Delete from './Delete.svelte'
  import Duplicate from './Duplicate.svelte'
  import Edit from './Edit.svelte'
  import Move from './Move.svelte'

  const menu = createMenu({ label: 'Actions' })

  function onChange(e: Event) {
    console.log('select', (e as CustomEvent).detail)
  }

  // prettier-ignore
  const groups = [
		[
			{ icon: Edit, text: `Edit` },
			{ icon: Duplicate, text: `Duplicate` },
		], [
			{ icon: Archive, text: `Archive` },
			{ icon: Move, text: `Move` },
		], [
			{ icon: Delete, text: `Delete` },
		],
	]
