How are modal navigation drawers used on mobile?
Modal navigation drawers use a scrim to block interaction with the rest of an app’s content. They are elevated above most app elements and don’t affect the screen’s layout grid. They are primarily for use on mobile, where screen space is limited. They can be replaced by standard drawers on tablet and desktop.
Bottom navigation drawers are modal drawers that are anchored to the bottom of the screen instead of the left or right edge. They are only used with bottom app bars. These drawers open upon tapping the navigation menu icon in the bottom app bar.
The navigation drawer slides in from the left and contains the navigation destinations for your app. An example of a popular Android app that implements the navigation drawer menu design is the Inbox app from Google, which uses a navigation drawer to navigate different application sections.
