If I place the menu widget into the "Simple Top Navigation" section and insert the code into my sidebar or header then the suckerfish dropdown works, but If I drag the menu widget into "Sidebar 1" then it just shows up as a text list with no suckerfish. Is that intended? If not, then maybe you could add an option to let non-TOP nav menus use suckerfish (I have a vertical suckerfish dropdown menu I want to drop into my sidebar). What would be really nice is if you could select what suckerfish css to use for each menu list, though I know that would be difficult.
Great plugin, I intend to use it, even if I have to use the TOP nav!
