ModalNavigationDrawer

Component in Material 3 Compose

Navigation drawers provide ergonomic access to destinations in an app.

Modal navigation drawers block interaction with the rest of an app’s content with a scrim. They are elevated above most of the app’s UI and don’t affect the screen’s layout grid.
