Accessibility #

It exposes status semantics, with aria-label, aria-labelledby, aria-pressed and aria-hidden kept in step with state. Changes that matter are announced through a live region.

Keyboard and focus handling comes from Radix popover: arrow keys move through items, Enter and Space select, and Escape closes and returns focus.

Motion #

It declares no animation in its component source. Any transition comes from its stylesheet, which uses the duration tokens that collapse to instant under prefers-reduced-motion.
