ShortNavigationBar

Common

Component in Material 3 Compose

Material Design short navigation bar.

Short navigation bars offer a persistent and convenient way to switch between primary destinations in an app.

The recommended configuration of the [ShortNavigationBar] depends on the width size of the screen it's being displayed at:

  • In small screens, the [ShortNavigationBar] should contain three to five [ShortNavigationBarItem]s, each representing a singular destination, and its [arrangement] should be [ShortNavigationBarArrangement.EqualWeight], so that the navigation items are equally distributed on the bar.
  • In medium screens, [ShortNavigationBar] should contain three to six [ShortNavigationBarItem]s, each representing a singular destination, and its [arrangement] should be [ShortNavigationBarArrangement.Centered], so that the navigation items are distributed grouped on the center of the bar.

A simple example of the first configuration looks like this:

@sample androidx.compose.material3.samples.ShortNavigationBarSample

And of the second configuration:

@sample androidx.compose.material3.samples.ShortNavigationBarWithHorizontalItemsSample

See [ShortNavigationBarItem] for configurations specific to each item, and not the overall [ShortNavigationBar] component.
