# Showcase

The flagship XWUIFeedbackBanner demo. It covers the four semantic variants, banners with zero, one, or several actions, the `showIcon` toggle versus a custom `icon` element, the `closable` state observed through `setOnClose`, and a live `setContent` update loop.

Each banner mounts into its own child div because an XWUI component clears its container on construct. `sticky` is turned off throughout so the banners lay out inline with the rest of the page instead of pinning to the viewport top.
