Dropdown Pages in header

I am currently using a Theme called alibi from BlogChemistry.com and while dated at 2008 I am guessing I can’t get the functionality of a drop down menu if not natively supported on the header. The previous them WP TwentyTen allowed me to have a parent page and sub pages, but it doesn’t look as if that is a possibility here. I have tried a few plugins, but since I have no header to place widgets I can’t use them. Am I just out of luck here and should look for another theme? The site is http://www.the6thfloor.com. Thanks.
