For different flows and dashboards tabs i use the inject after 0.2 secs so that drop down menus will be filled. However the tabs which are not initially shown do not show the drop down menus. When i then inject again the drop down menus are filled. Is there a way that i can see this all drop down menus without a second by hand inject?

Instead of inject, use a change node & trigger that with a UI\_CONTROL node set to fire an event when user switches TAB.
