Are there any tutorials out there or samples of a simple CCS Dropdown Menu?

I recently built a simple menu bar which looks like a series of (horizontal) rectangles. When you hover over one, it turns color. And each rectangle is like a "tab" that leads to a section in my website.

So now I would like to expand, and have a submenu for each main menu item. For example, I have an item "SHIRTS" and I would like a vertical dropdown that displays:

Men's
Women's
Kids'

I want to steer clear of JavaScript since I don't know it, and away from CSS3 since I need to be backwards compatible to IE6.

No fancy effects. Just a simple solid color, rectangular drop-down menu like you would find in most applications you use on your computer.
