shadcn.io is an independent project built on shadcn/ui
The trail reads Home, then a folder button, then Components, then Breadcrumb as the current page. The folder opens Documentation, Themes, and GitHub. The button is named Show sections.
Use it when the collapsed levels must stay reachable. An ellipsis is enough if they can be dropped. Sibling pages that are one value fit a Select. In React, Base UI does not fill the menu from the route.

How is the menu built?
DropdownMenu wraps a DropdownMenuTrigger and a DropdownMenuContent with align="start" and three DropdownMenuItems.
How is the folder button named?
Its only child is a FolderIcon, hidden from assistive tech, so the button carries aria-label="Show sections". Without it the button would have no name.
Do the menu items navigate?
Not in the demo: they are plain items. Make each one a link to its section, or handle the selection and route from there.
How is the trail announced?
Breadcrumb renders a nav labeled breadcrumb around an ordered list, so screen readers announce a breadcrumb landmark and the number of items. Home and Components are read as links.
