In our application, we are using the menu to dislay a hierachical list of products from which the users can select. Our problem is that the heirarchy for each client is significantly different. One client will have only a couple levels with a few items per level. Others may have 5 levels, and any individual level may have 30 or more items. The problem comes in when the menu positioning code opens the subwindow, if it's longer than the viewable area of the screen, the menu essentially grows the page, but the bottom of the menu will not be visible. If you are not using a mouse with a scroll wheel, it can become impossible to navigate parts of the menu. Because of the nature of the data we're using, reorganizing the menu is not really an option. What would be ideal for us would be to be able to set a limit on the number of items to display at a time (say 10), and have the menu be able to scroll inside of itself. (I've seen feature in other menus, but none were as cool as this one:).
