The menu items inside the role="menu" container should have role="menuitem" to properly implement the ARIA menu pattern. Without this, screen readers won't correctly identify these as menu items.

The input type should be "search" for semantic HTML, not "text". The HTML specification defines the search input type which provides better semantics for assistive technologies.

The aria-label should start with a capital letter and be more descriptive to match the standard pattern. Consider using "Search" instead of "search" for consistency with other ARIA labels in the codebase.

The ellipsis span has an aria-label but the icon inside is marked aria-hidden="true". This creates a conflict where screen readers will announce "More pages" but the visual content is hidden from assistive technology. Since the ellipsis is purely decorative and doesn't provide navigation, the entire span should be marked with aria-hidden="true" instead of having an aria-label.
| aria-label="More pages" | |
| aria-hidden="true" |

| aria-label={`${link.text} menu`} | ||
| aria-expanded={isOpen} | ||
| aria-haspopup="true" |

The aria-haspopup value should be "menu" to match the role="menu" on the dropdown container. Currently it's set to "true" which is equivalent to "menu", but using the explicit string value improves clarity and follows ARIA best practices.
