Menu issue

Hi all,
When we add a couple of levels of sub items to a menu item for properties(4 different menu items on the main menu) the first level of sub items for Properties appears indented( subitems are For Rent, For Sale) but that places it under the next main menu item (Book). Its extremely hard to select either of those two sub items. Is there anyway to pull those first level of sub items directly under properties and then allow the subitems for Rent and For Sale to be indented.
