TOPIC: Expanded menu items

A few of my menu items have sub-menus.  
When editing these menus, at the bottom of "menu settings" is a line that says; "You may also edit the advanced settings for this menu item."  There I set for the menu not to be expanded.  I can't find a place to do this for the Image galleries.  Do they have to be expanded all the time?  
(The reason I would like them not to be expanded is so the navigation column doesn't look so large.  I figure visitors are more likely to brows the navigation column if it isn't as long as my arm.  Faulty or good reasoning?)

Thanks

Usually people just have one link for the photo galleries. Go ahead and just manually create a menu link to each.
