fix div issue

i have add new image slider on the top of my site but i can't keep it exactly under the menu and my menu are behind this too .
any body can fix this issue ?

Try .dropmenu li {
float:left;
list-style:none outside none;
margin:0;
padding:0;
position:relative;
z-index:10;
}

of course still the image slider is not under the menu .

It works for me in FF3.6. Which is your browser? Have you updated the CSS of your online version?

i have internet explorer 7 and last stable version of firefox but in both of them image slider is not under the effect menu and image slider is middle of the page like this :
