I'm looking to get drop-downs from the navbar menu. I've installed webcouturier.dropdownmenu, which seemed to be the way to go for that. I added it to the eggs, ran the buildout, went into Site Settings > Add-Ons and installed it, went into Site Settings > Add-On Settings > Dropdown Menus and looked over the settings, verified that they all seem good, saved them, etc. During this process I didn't encounter any errors or other unexpected behaviour, but it doesn't seem to do anything.
Worth noting is that the function to disable clicking on anything with children, from its control panel, DOES work. If I turn it on, I can't click on any navbar folder that has children. If I disable it, the behaviour reverts to normal. However, nothing else happens -- no drop-down menus whether I hover over the menus, click on them, etc.
