# Showcase

The flagship XWUINavigationRail demo. It walks through a basic rail, a fully interactive one driven by `onClick` / `setActiveItem`, an href-linked rail with a bespoke-styled item, and per-instance RTL direction.

The rail renders `position: fixed` at the viewport bottom by design (it is a mobile tab bar), so each demo resets its element to sit inline inside its own showcase panel instead of pinning to the page edge.
