Drop down menu questions

http://arcticcat.com/snow/arcticwear.asp

I know how to make a drop-down like the one here, (mouse over ‘riders only’) but I dont know how they made it roll on top of the html page? Can anyone help!

The content for the CSS is set at z-index 0, the flash nav is set at z-index 1. And the flahs movie is set at wmode=transparent. Check out the source, its all there for ya. :wink:

I took a look at the source+css, and I have a couple of questions. If the z-index of the header is 1, which would place it higher than the content, was it necessary for them to place the div lower in the code? And why do both the divs need to be set with an ‘absolute’ position? They also set their flash height to 100%, why is that done?

im a bit lost
