TanStack

Dropdown

A menu built on Base UI primitives, composed from Dropdown + Trigger + Content + Item + Separator. Source: src/components/ds/ui/index.tsx.

Basic menu

Click the trigger to open. Content is portaled and keyboard-navigable.

Scrollable

Pass `maxHeight` to cap a long menu. Overflow reveals a thin, low-opacity scrollbar meant to read only as a 'more content' indicator — not a grab target.
