# Showcase

The flagship XWUIGameMailUI demo. It walks through the two-column list/reader layout, the `showAttachments` and `showCompose` toggles, unread badges versus an all-read inbox, and external control through `delete()` alongside the `onRead` / `onCompose` / `onDelete` callbacks.

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