Navigation Menu
A site nav with flyout content panels that open below the bar. Supports rich panel content alongside plain links with aria-current.
With flyout panels
Clicking a trigger opens a content panel below the entire nav bar. Clicking another trigger switches the panel. Escape or clicking outside closes it. Plain links render inline without a flyout.
Links only
Use NavigationMenuLink directly for items that don't need a flyout. Pass active to mark the current page — sets aria-current="page".
