jquery dropdown, content in neighbour

Usually, when you enter the menu, you are allowed to browse menu items. In this code it is not working:

Is it because the items are no开发者_StackOverflow社区t inside menu element? If so, could it be solved in jQuery, instead of moving the code?

Thanks.

works well with Superfish plugin
