The app bar & header component is a dedicated bar at the top of the app canvas that can be customized to display important app-related functions, such as branding, top-level navigation, and access to app controls.
Use consistent app bar & header layouts to place key controls, such as in-app search, in a standard location throughout the UI.
Anatomy
The app bar & header can include a variety of elements. It can be configured in either of these ways:
- App header: When configured as an app header, the component contains space for optional text, with minimal use of icons and buttons. Typically, it includes a screen title and back arrow.
- App bar: When configured as an app bar, it can include icons, tabs, and buttons. Typical elements include an app icon and navigational options.
Either of these versions may also include app controls, such as in-app search and settings.
