The auro-menu component renders with role="listbox". Each auro-menuoption renders with role="option". This semantic structure allows assistive technologies to communicate the list of options and their states.

Menu options communicate their state to assistive technologies:

• Selected: The aria-selected attribute is set to true on the selected option(s).
• Disabled: The aria-disabled attribute is set to true on disabled options, preventing interaction.
• Hidden: Options with the hidden attribute are removed from the accessible tree.

The menu supports full keyboard navigation:

• Arrow Down / Arrow Up: Moves the active option.
• Enter: Selects the currently active option.
• Tab: Selects the currently active option and moves focus out of the menu.

See the Keyboard Behavior page for full details.

The Meta key (Command on macOS, Windows/Super elsewhere) is intentionally not used as a modifier for menu keyboard shortcuts. On Windows, Linux, and ChromeOS, the operating system intercepts Meta + Arrow combinations for window management (e.g. window snapping) before the browser receives the event, so any shortcut bound to Meta + Arrow would work only on macOS and silently fail on other platforms.

To jump to the first or last option in a way that works uniformly across platforms, use Home and End, which follow the WAI-ARIA Listbox pattern.

When the multiselect attribute is set, aria-multiselectable="true" is applied to the menu, allowing multiple options to be selected. Each option's aria-selected attribute reflects its individual selection state.
