Vertical Menus? (and menus within menus etc.)

*give option to display Menu Vertically (or horizontally, as it currently is offered) on left side of user interface.

This would help UI display when I have a Menu within a Menu.

See Example Renter Dashboard with "My Application" Tab selected

user must be logged in: Login "" pw: "12345"

*re: Menus within Menus: currently the "parent" menu disappears when a child menu is selected. Consider adding ability to keep Parent Menu visible when navigating through sub-menu.
