# Showcase

The flagship XWUIListMaster demo. It walks through the plain read-only table, the cumulative action model (header add plus per-row view, edit and delete icon buttons gated by the four `action_*_state` toggles), hiding columns with `cols` while keeping the underlying row data intact, and the built-in `json` state that exports the column and row model.

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