When navigating to another screen with clicking on the button, the Top bar is reappears itself again.
(See screenshot below)
Aim would be to hide the #top bar permanently - not reappearing after #navigation to another screen.
Since the Board Reports are going to be implemented in an existing #web #portal. It is not an option to link each screen by a single #iFrame-Link since then we cannot use major BOARD features e.g. #Drill to Screen Function, #transfer selections etc.
