I have a lone menu item that is to the far right of the screen. The menu item's dropdowns are 4-tiered (Main Menu -->Sub Menu-->Sub-Sub Menu-->Sub-Sub-Sub Menu) and it actually runs of the right side of the screen. 

Is there a way to make the menu item's dropdowns collapse to the left instead of the right to keep the menu on the page?

I hope I explained it well. Thank you in advance.
