# Showcase

The flagship XWUIListRecordMaster demo. It walks through a basic records table driven by a form definition, the row-action model with record-typed callbacks (`onViewRecord`, `onEditRecord`, `onDeleteRecord`, `onAddRecord`), hiding a column with `cols`, capping a wide form definition to its first fields with `maxColumns`, and the inherited `json` export state.

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