MenuItems - Building Accessible Menus with ARIA Part II

Shawn Sandy (Ally.Cafe) ~

Introduction to Menuitem Role

The menuitem role is an essential part of ARIA (Accessible Rich Internet Applications) that defines an item within a menu or menubar. It is used to provide accessible navigation and interaction for users with disabilities, particularly those who rely on screen readers and keyboard navigation.

Why Menuitem Accessibility Matters

Making menu items accessible ensures that:

  • Screen Reader Users can understand and interact with menu options.
  • Keyboard-only Users can navigate through menu items efficiently.
  • Users with Cognitive Disabilities can easily comprehend and use the navigation options.

WCAG Guidelines Relevant to Menuitem

Key WCAG 2.2 guidelines to consider for menu items include:

  • Perceivable: Making information and user interface components presentable to users in ways they can perceive.
    • 1.3.1 Info and Relationships: Ensuring that information, structure, and relationships conveyed through presentation can be programmatically determined.
  • Operable: Ensuring that user interface components and navigation are operable.
    • 2.1.1 Keyboard: Making all functionality accessible via a keyboard interface.
    • 2.4.3 Focus Order: Ensuring that components receive focus in an order that preserves meaning and operability.
    • 2.4.6 Headings and Labels: Providing headings and labels that describe the topic or purpose.

ARIA Role: menuitem

The menuitem role in ARIA is used to define individual items within a menu. These items can be actionable commands, links, or submenus.

Implementation and Best Practices

Here’s how you can implement a menuitem using ARIA roles and attributes:

Example Code

<nav role="menubar" aria-label="Main Menu">
  <div role="menuitem" tabindex="0" aria-haspopup="true" aria-expanded="false">File</div>
  <div role="menuitem" tabindex="0" aria-haspopup="true" aria-expanded="false">Edit</div>
  <div role="menuitem" tabindex="0" aria-haspopup="true" aria-expanded="false">View</div>
</nav>

<!-- Example of a submenu -->
<div role="menu" aria-label="File Submenu">
  <div role="menuitem" tabindex="-1">New</div>
  <div role="menuitem" tabindex="-1">Open</div>
  <div role="menuitem" tabindex="-1">Save</div>
</div>

Key Points

  • role=“menuitem”: Defines each interactive element within a menu or menubar.
  • tabindex=“0”: Makes the menu item focusable and accessible via keyboard.
  • aria-haspopup=“true”: Indicates that the menu item can open a submenu.
  • aria-expanded=“false”: Indicates the current state of the submenu (collapsed or expanded).

Sufficient Techniques and Failures

Sufficient Techniques

  • Using role="menuitem": Appropriately define each menu item.
  • Implementing keyboard navigation: Ensure users can navigate using arrow keys and tab through items.
  • Providing clear focus indicators: Use visual indicators to show which menu item is currently focused.

Common Failures

  • Failure to include keyboard support: Not allowing users to navigate menu items using only the keyboard.
  • Incorrect ARIA roles: Using roles that do not correctly describe the element’s function.
  • Lack of proper focus management: Making it difficult for keyboard users to navigate due to improper focus order.

Screen Reader Support and Compatibility

Ensuring compatibility with various screen readers is crucial. Common screen readers include:

  • JAWS: A popular screen reader for Windows.
  • NVDA: A free screen reader for Windows.
  • VoiceOver: Built-in screen reader for macOS and iOS.
  • TalkBack: Built-in screen reader for Android.

Best Practices

  • Test with Multiple Screen Readers: Ensure the menu items work well across different screen readers.
  • Focus Management: Implement logical focus order and use ARIA attributes to manage focus correctly.
  • Keyboard Accessibility: Ensure all menu items are navigable via keyboard.

Conclusion

Making menu items accessible is essential for creating inclusive web applications. By following WCAG guidelines and using ARIA roles correctly, developers can ensure that all users, regardless of their abilities, can navigate and interact with menu items effectively.
