I'm using the default Gantry framework template on J1.5.23.
I added a div in order to make the header and topmenu stay fixed at the top.
This however causes problems with the horizontal fusionmenu: when scrolling down a bit, it is not possible to see the dropdownmenu anymore when hovering over a root item.
Also when you are hovering the submenu and then start scrolling with the mouse scrollwheel, you can see the submenu dropdown dissapear (it's moving to the top over the header right out of the screen).
Does anybody know how I can prevent the dropdownmenu from acting this way? Would I need to include more divs or maybe move the fusionmenu position in some file?
