# Showcase

The flagship XWUIShellPart demo. It walks through a basic dockable region with a draggable divider, the four presence states driven by `show` / `collapse` / `expand` / `hide`, the flow axis switched live between inline and floating, the capability-flag controls (`detachable` / `tabbable` / `splittable`) and their emitted events, and the orthogonal visual-state modifiers (`bordered`, `shadow`, `elevated`).

Every part mounts into its own child div because an XWUI component clears its container on construct.
