# Showcase

The flagship XWUITaxBreakdown demo. It walks through a single tax line, multiple stacked tax groups with a hover note, the default/outlined/filled variants, compact density for narrow panels, editable inline amounts with live `onTaxAmountChange` recomputation, and a non-USD locale with custom row labels.

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