Standard / Persistent Bottom Sheet
also known as persistent bottom sheet
A standard (persistent) bottom sheet rests at the same elevation as the app and integrates with its layout, so it stays on screen and you can interact with both it and the main content at once. There's no scrim. It suits secondary content you want continuously accessible, especially when the main area scrolls.
Don't confuse it with
The key difference from a modal bottom sheet: a standard sheet has no scrim and doesn't block interaction, coexisting with the main UI. Because it's part of the layout it behaves more like a movable panel than a temporary overlay.
In the wild
The Google Maps place-details panel you can drag up while still panning the map is a persistent bottom sheet.
