Here is the link to the domain http://linenwoods.com I am working on. I am going to fit the navigation list items on the header, but when the drop down menu is implemented I'm pretty sure it'll go under the #main div like you see currently. Is there any easy way fix to this? I couldn't find anything related to this from a google search .. was hoping someone could help me out. Below is the relevant CSS .. I tried playing around with z-index with no luck as I was told IE8 renders it strangely. If you have the time please follow the link with IE and leave a response .. I am trying to be as cross-browser compatible as possible and already am at a pretty pathetic start. Any help would be appreciated :)

background-image:url('Background1.jpg');
background-position: center;
height: 100%;
margin: 0;

}

#main {
width : 1010px;

margin-top: 15px;
