The tree view contains tabs with the available areas. They are organized in a hierarchy, from state > federal state > administrative district to county. Next to the state name, in brackets, is a state number. If a value is not available, only the "Not specified" text is displayed.
Select a tab in the tree view to display data of the next tab in the hierarchy. For example, if "Germany" state is selected, all federal states in Germany are displayed, but only if their data is available. The information will be displayed in the upper left table.
In particular, all states are displayed when selecting the topmost element address management and all municipalities in the district are displayed when selecting a district.
