# ExpandedSurfaceBox

Host-aligned container for an ExpandedSurfaceProviding view.

`@MainActor struct ExpandedSurfaceBox<Content> where Content : View`

Propagates [`ShelfWidgetLayout`](https://getdroppy.app/docs/droppykit/api/shelf-widget-layout) derived from the [`ExpandedSurfaceContext`](https://getdroppy.app/docs/droppykit/api/expanded-surface-context) (including any cutout-wrap bands) so [`ShelfWidgetHeader`](https://getdroppy.app/docs/droppykit/api/shelf-widget-header), [`ShelfWidgetScaffold`](https://getdroppy.app/docs/droppykit/api/shelf-widget-scaffold), [`ShelfWidgetStageScaffold`](https://getdroppy.app/docs/droppykit/api/shelf-widget-stage-scaffold), and Droppy wash controls mask and clear the camera cutout identically to shelf widgets.

Available from DroppyKit 1.24.0; a droplet that uses it declares `minAPI` 1.24.0.
