Drop Down Menu

[CLP]

I am trying to create a drop down vertical navigation menu similar to the one on the left hand side at www.restockit.com. I am not a very experienced designer, but if I am pushed in the right direction I can usually figure things out.

Please help as I am trying to meet a deadline for my boss.

I also posted this in another section. I tried to delete it, but couldn't figure it out. Sorry.
