# Drop-In UI

![A Navigation UI displaying the primary maneuver, secondary maneuver, maneuver icons, step distance remaining, and upcoming maneuver list as described above.](https://docs.mapbox.com/android/ja/assets/ideal-img/navigation-drop-in-ui-general.0157dc0.480.png) 

Drop-In UI is a pre-made navigation layout composed of standalone Navigation Core and UI components the SDK has to offer, with a Mapbox Map underneath. The system implements all stages of navigation and transitions between them, and facilitates integration using few lines of code. Drop-In UI gives you enough customization options to keep your branding, and to replace standalone Navigation UI components with custom made ones to support the unique needs of your use case.
