      <MenubarPortal>
        <MenubarContent>
          <MenubarItem>
            <img src="…">
            Adolfo Hess
          </MenubarItem>
          <MenubarItem>
            <img src="…">

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-menubar-trigger-width and --reka-menubar-content-available-height to support this. Use them to constrain the content dimensions.

vue

<script setup lang="ts">
import { MenubarContent, MenubarItem, MenubarMenu, MenubarPortal, MenubarRoot, MenubarTrigger } from 'reka-ui'
</script>

<template>
  <MenubarRoot>
    <MenubarMenu>
      <MenubarTrigger> Trigger </MenubarTrigger>
      <MenubarPortal>
        <MenubarContent
          class="MenubarContent"
          :side-offset="5"
          :align-offset="-3"
        >
          <MenubarItem> New Tab </MenubarItem>
        </MenubarContent>
      </MenubarPortal>
    </MenubarMenu>
  </MenubarRoot>
</template>

css

/* styles.css */
.MenubarContent {
  width: var(--reka-menubar-trigger-width);
  max-height: var(--reka-menubar-content-available-height);
}

Origin-aware animations

We expose a CSS custom property --reka-menubar-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 { MenubarContent, MenubarMenu, MenubarPortal, MenubarRoot, MenubarTrigger } from 'reka-ui'
</script>

<template>
  <MenubarRoot>
    <MenubarMenu>
      <MenubarTrigger>…</MenubarTrigger>
      <MenubarPortal>
        <MenubarContent class="MenubarContent">
          …
        </MenubarContent>
      </MenubarPortal>
    </MenubarMenu>
  </MenubarRoot>
</template>

css

/* styles.css */
.MenubarContent {
  transform-origin: var(--reka-menubar-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 { MenubarContent, MenubarMenu, MenubarPortal, MenubarRoot, MenubarTrigger } from 'reka-ui'
</script>

<template>
  <MenubarRoot>
    <MenubarMenu>
      <MenubarTrigger>…</MenubarTrigger>
      <MenubarPortal>
        <MenubarContent class="MenubarContent">
          …
        </MenubarContent>
      </MenubarPortal>
    </MenubarMenu>
  </MenubarRoot>
</template>

css

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

Key	Description
`Space`	When focus is on `MenubarTrigger`, opens the menubar and focuses the first item. When focus is on an item, activates the focused item.
`Enter`	When focus is on `MenubarTrigger`, opens the associated menu. When focus is on an item, activates the focused item.
`ArrowDown`	When focus is on `MenubarTrigger`, opens the associated 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 a `MenubarTrigger`, moves focus to the next or previous item. When focus is on a `MenubarSubTrigger`, opens or closes the submenu depending on reading direction. When focus is within a `MenubarContent`, opens the next menu in the menubar
`Esc`	Closes the currently open menu and moves focus to its `MenubarTrigger`.
