Product UI Kit
Product FABs / Floating Actions
ProductFloatingActionButton and ProductMapActionPlacement are the accepted Product UI Kit floating-action masters, with shared dark glass, translucent hover, 8px blur and the floating-action shadow. ProductFloatingActionPlacement remains a source-only layout mechanic used by page layouts; Search / Catalog runtime placement, labels, counts, and callbacks remain adapter-owned.
FABs / Floating Actions
ProductFloatingActionButton primitive
Destination action
Up, map/list, expand/return and zoom actions share this material; wrappers own placement and callbacks.
Disabled state
Disabled behavior remains owned by the primitive.
Map action placement
ProductMapActionPlacement
ProductMapActionPlacement / bottom center
Placement owns geometry only; callers own count, state, and callback.
