How do I put homepage slider behind dropdowns

As my last post was so helpful with the slider setup! Here goes.

I have another questions relating to the same slider. So I am just starting to setup a new site. I have installed easy slider http://www.NewbornMagazine.com

I installed the slider (just a temp image and size but anyway - The slider appears in front of the drop down menus on the top of the page. I could add enough padding for it not to be an issue but then it will not look as visually appealing.

Any thoughts on how i send that to the back so that the drop down menu would appear in the front?

Here is a link to how I place the slider there:
