Hi, I'm using the CSS Top Menu from Javascript Kit and trying to customize it. The problem I have is that I want the menu drop-downs to be separate from the header links (not much separation, but more than the default setting), but if I set the "top" attribute in submenus style to great than 1.4 em, the menus will display, then behave strangely (can't select the contents, etc.) I also need to modify this so the menus will be separate in Firefox and other non-IE browsers. So I'm looking for a solution. Any ideas?

Here's my code so far:

Code:
<style type="text/css">

#csstopmenu, #csstopmenu ul{
padding: 0;
margin: 0;
list-style: none;
}

#csstopmenu li{
float: left;
position: relative;
}

#csstopmenu a{
text-decoration: none;
}

.mainitems{
border-right: 1px solid #cccccc;
border-bottom: 1px solid #cccccc;
border-left-width: 0;
background-color: #ffffff;
font-family: Arial, Helvetica, sans-serif; font-size: 11px; font-weight: bold; color: #000000;
}

.headerlinks {
margin: auto 8px;
font-family: Arial, Helvetica, sans-serif; font-size: 11px; font-weight: bold; color: #000000;
color: black;}

.headerlinks a:hover{
background-color: #ffffff;
color: #FF0000;
}

.submenus{
display: none;
width: 15em;
position: absolute;
top: 1.4em;
left: 0;
background-color: #f6f6f6;
border-right: 1px solid #cccccc;
border-bottom: 1px solid #cccccc;
border-left: 1px solid #cccccc;
font-family: Arial, Helvetica, sans-serif; font-size: 11px; font-weight: normal; color: #000000;
}

.submenus li{
width: 100%;
}

.submenus li a{
display: block;
width: 100%;
text-indent: 8px;
}

html>body .submenus li a{ /* non IE browsers */
width: auto;
}

.submenus li a:hover{
background-color: #f6f6f6;
color: #FF0000;
}

#csstopmenu li>ul {/* non IE browsers */
top: auto;
left: auto;
}

#csstopmenu li:hover ul, li.over ul {
display: block;
}

html>body #clearmenu{ /* non IE browsers */
height: 3px;
}
</style>
