This Enhancement shall allow to activate a new menu list behavior to drop the menu on screen when pushing the list icon. Therefore we will implement a new option in the course editor; see also attached Screenshot. Once this checkbox is selected, the menu is visible only as an icon (as implemented for the responsive design, when OO running on a small device/display. The new behavior schows this reduced menu icon as long as we're not clicking on the icon.
Further discussion necessary about the hamburger placement and the question how we jump back into the hamburger menu once the menu is expanded.
