I'm working on a new site design with the Transparent - Horizontal theme and theme overrides. This design uses the drop down navigation and some on page navigation in place of the second level navigation, which is hidden. This is working well, except that by default the drop down does not work on the actively selected top level navigation item. Is there a place in the theme where I can alter this to allow the actively selected menu item to continue to offer a drop down when selected?
