Behavior and Interaction
When the user taps on a destination or if one is focused on the navigation bar, the user is directed to the navigation destination associated with that icon. Navigation between destinations is visually highlighted by the active indicator and the filled icon.
Use navigation bars on mobile and small tablet interfaces. The navigation bar uses 100% of the screen width and the destinations are equally distributed across the navigation bar.
On tablets, replace the navigation bars with a more appropriate component, such as a navigation rail or navigation drawer.
There are different variations of destinations to represent the navigation bar:
- Label and icon
- Icon only
- Label and icon for selected destinations and icon only for unselected destinations
Label and Icon
The default navigation bar consists of a label and an icon.
For a simplified navigation bar, you can omit the labels. Icons should always be unique and universally represented for users (e.g., basket, home and favorites).
The mixed variation is used to emphasize the selected destination with label and icon and the unselected destinations are displayed with icon only. Use this variation only when the icons have a clear meaning to users.
