I am having a strange issue when I am using Responsive Navigation with Drilldown (with Foundation 6).
The issue is that when the Drilldown menu is exposed it's height is determined by the height of the largest ul. One of my sub-menu is 12 items long, but the initial top level menu is only 6. This make the menu have a min-height of 1045px, and lots and lots of blank, white space.
Does anyone know a way to collapse the submenus until they are exposed?
