 ### Menu (Drop Down)
 
+The navigation bar at the top of each page displays always all the parts. If a part's page is shown the corresponding navigation bar element is shown activated.
+
+On the left of the navigation bar is a special item. It displays the text that is configured under ``params.title`` in the ``config.yaml`` (or ``.toml`` or ``.json``) of your site. 
+
+If you want a dropdown menu under it configure it in the ``config.yaml`` (or ``.toml`` or ``.json``) of your site:
+
+    params:
+      dropdown: 
+        - entry1:
+          url: /
+          linktext: Overview
+        - divider2:

+        - entry9:
+          url: /index.xml
+          linktext: RSS
+
+The list of entries under dropdown will be used to construct te dropdown menu. Every entry that has no ``url`` or no ``linktext`` will be interpreted as an divider.
+
+If the ``params.dropdown``  list is not set then the site tile will have a link to the home page (``/index.html``).
