API Reference

Root

Constrain the content/sub-content size

You may want to constrain the width of the content (or sub-content) so that it matches the trigger (or sub-trigger) width. You may also want to constrain its height to not exceed the viewport.

We expose several CSS custom properties such as --reka-dropdown-menu-trigger-width and --reka-dropdown-menu-content-available-height to support this. Use them to constrain the content dimensions.

vue

<script setup lang="ts">
import { DropdownMenuContent, DropdownMenuPortal, DropdownMenuRoot, DropdownMenuTrigger } from 'reka-ui'
</script>

.DropdownMenuContent {

  max-height: var(--reka-dropdown-menu-content-available-height);
}

Origin-aware animations

We expose a CSS custom property --reka-dropdown-menu-content-transform-origin. Use it to animate the content from its computed origin based on side, sideOffset, align, alignOffset and any collisions.

vue

<script setup lang="ts">
import { DropdownMenuContent, DropdownMenuPortal, DropdownMenuRoot, DropdownMenuTrigger } from 'reka-ui'
</script>

<template>
  <DropdownMenuRoot>
    <DropdownMenuTrigger>…</DropdownMenuTrigger>
    <DropdownMenuPortal>
      <DropdownMenuContent class="DropdownMenuContent">
        …
      </DropdownMenuContent>
    </DropdownMenuPortal>
  </DropdownMenuRoot>
</template>

css

/* styles.css */
.DropdownMenuContent {
  transform-origin: var(--reka-dropdown-menu-content-transform-origin);
  animation: scaleIn 0.5s ease-out;
}

@keyframes scaleIn {
  from {
    opacity: 0;
    transform: scale(0);
  }
  to {
    opacity: 1;
    transform: scale(1);
  }
}

Collision-aware animations

We expose data-side and data-align attributes. Their values will change at runtime to reflect collisions. Use them to create collision and direction-aware animations.

vue

<script setup lang="ts">
import { DropdownMenuContent, DropdownMenuPortal, DropdownMenuRoot, DropdownMenuTrigger } from 'reka-ui'
</script>

<template>
  <DropdownMenuRoot>
    <DropdownMenuTrigger>…</DropdownMenuTrigger>
    <DropdownMenuPortal>
      <DropdownMenuContent class="DropdownMenuContent">
        …
      </DropdownMenuContent>
    </DropdownMenuPortal>
  </DropdownMenuRoot>
</template>

css

/* styles.css */
.DropdownMenuContent {
  animation-duration: 0.6s;
  animation-timing-function: cubic-bezier(0.16, 1, 0.3, 1);
}
.DropdownMenuContent[data-side="top"] {
  animation-name: slideUp;
}
.DropdownMenuContent[data-side="bottom"] {
  animation-name: slideDown;
}

@keyframes slideUp {
  from {
    opacity: 0;
    transform: translateY(10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

@keyframes slideDown {
  from {
    opacity: 0;
    transform: translateY(-10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

Accessibility

Adheres to the Menu Button WAI-ARIA design pattern and uses roving tabindex to manage focus movement among menu items.

Keyboard Interactions

Key	Description
`Space`	When focus is on `DropdownMenuTrigger`, opens the dropdown menu and focuses the first item. When focus is on an item, activates the focused item.
`Enter`	When focus is on `DropdownMenuTrigger`, opens the dropdown menu and focuses the first item. When focus is on an item, activates the focused item.
`ArrowDown`	When focus is on `DropdownMenuTrigger`, opens the dropdown menu. When focus is on an item, moves focus to the next item.
`ArrowUp`	When focus is on an item, moves focus to the previous item.
`ArrowRightArrowLeft`	When focus is on `DropdownMenuSubTrigger`, opens or closes the submenu depending on reading direction.
`Esc`	Closes the dropdown menu and moves focus to{' '} `DropdownMenuTrigger`.

Custom APIs

Create your own API by abstracting the primitive parts into your own component.

Abstract the arrow and item indicators

This example abstracts the DropdownMenuArrow and DropdownMenuItemIndicator parts. It also wraps implementation details for CheckboxItem and RadioItem.

Usage

vue

<script setup lang="ts">
import {
  DropdownMenu,
  DropdownMenuCheckboxItem,
  DropdownMenuContent,
  DropdownMenuGroup,
  DropdownMenuItem,
  DropdownMenuLabel,
  DropdownMenuRadioGroup,
  DropdownMenuRadioItem,
  DropdownMenuSeparator,
  DropdownMenuTrigger,
} from './your-dropdown-menu'
</script>

<template>
  <DropdownMenu>
    <DropdownMenuTrigger>DropdownMenu trigger</DropdownMenuTrigger>
    <DropdownMenuContent>
      <DropdownMenuItem>Item</DropdownMenuItem>
      <DropdownMenuLabel>Label</DropdownMenuLabel>
      <DropdownMenuGroup>Group</DropdownMenuGroup>
      <DropdownMenuCheckboxItem>CheckboxItem</DropdownMenuCheckboxItem>
      <DropdownMenuSeparator>Separator</DropdownMenuSeparator>
      <DropdownMenuRadioGroup>
        <DropdownMenuRadioItem>RadioItem</DropdownMenuRadioItem>
