To make a large number of POIs appear more structured and not cluster the view too much, [[SYSCLS_POIGROUP|POI groups]] are introduced. POI groups aggregate the contained POIs and display only one POI as a substitute for all of them until the POI group is expanded ("entered").A POI group can be entered so that only those POIs that belong to that group can be are displayed. The only exceptions are those that don't belong to any group, which are displayed all the time.A building is a special type of POI group which consists of several building levels. Each level itself behave behaves similar to a group in the sense that multiple POIs can belong to it and, therefore, are only displayed when the level is active.
Once a POI group or a building is entered, some additional options become available on the left side of the POI view.
