NavigationDrawer

Component in Tv Material Compose

Navigation drawers provide ergonomic access to destinations in an app. They’re often next to app content and affect the screen’s layout grid. Standard navigation drawers are good for frequent switching to different destinations.

It displays content associated with the closed state when the drawer is not in focus and displays content associated with the open state when the drawer or its contents are focused on. The drawer is at the same level as the app's UI an reduces the screen size available to the remaining content.
