Persistent peek bar
Combine defaultOpen, dismissible={false}, modal={false}, snapPoints, and Drawer.Handle to build the "peek bar" pattern used by Apple Maps and Apple Music: a sheet that lives at the bottom of the screen, snaps between a peek view and a full view, and never closes.
The peek bar sits at the bottom of the viewport while you read this page. Drag the handle to expand it. Snap index: 0.
What each prop is doing
defaultOpenmounts the drawer in the open state on first render so the peek view is visible immediately.dismissible={false}blocks Escape, the overlay tap, and drag-to-close. There is no way for the user to dismiss the bar.modal={false}keeps the rest of the page interactive and scrollable so the bar truly behaves like a docked bottom bar instead of a sheet over a dimmed page.snapPointscontrols how far the bar expands. The first snap should match the peek height; later snaps reveal more of the content.Drawer.Handlegives the user something to grab. Without it the bar is not visibly draggable.
Reserve space for the bar
Because the bar overlays the bottom of the viewport, content at the bottom of the page can be hidden behind it. Add bottom padding equal to the peek height to your page wrapper:
