CSS Examples 2-level CSS Drop Down Menu

Date: 12/09/2004 2-level CSS Drop Down Menu

Author: CSS Drive (based on SuckerFish menu)

This is a two level CSS Drop Down menu powered entirely by CSS- well, almost. Since IE (as of IE6) doesn't yet support the ":hover" pseudo class on anything other than links, a little JavaScript is required to bind the menu together in those browsers. Based on the SuckFish menu code, though I've modified it with a few changes and improvements of my own, such as visual styling, and the ability to change the width of the drop down menus individually.

The CSS and JavaScript:

<style type="text/css">

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

#cssdropdown li {
float: left;
position: relative;

border: 1px solid black;
background-color: #FFEEC6;

.mainitems a{
margin-left: 6px;
margin-right: 8px;
text-decoration: none;

display: none;
width: 10em;
position: absolute;
top: 1.2em;
left: 0;
background-color: lightyellow;
border: 1px solid black;

.subuls li{
width: 100%;

.subuls li a{
text-decoration: underline;

#cssdropdown li>ul { /* to override top and left in browsers other than IE, which will position to the top right of the containing li, rather than bottom left */
top: auto;
left: auto;

#cssdropdown li:hover ul, li.over ul { /* lists nested under hovered list items */
display: block;

#restofcontent { /*wrap rest of content of the page inside this div*/
clear: left;


<script type="text/javascript"><!--//--><![CDATA[//><!--
startList = function() {
if (document.all&&document.getElementById) {
cssdropdownRoot = document.getElementById("cssdropdown");
for (x=0; x<cssdropdownRoot.childNodes.length; x++) {
node = cssdropdownRoot.childNodes[x];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
node.onmouseout=function() {
this.className=this.className.replace(" over", "");

if (window.attachEvent)
window.attachEvent("onload", startList)

This drop down requires the use of a mouse. Is it possible to drop down on tab?

Example not working. I have Internet Explorer 7.0 and I cannot access the drop downs when trying to move over to them because they are too far away. The mouse over has gaps of space between the tabs and the drop downs making the drop downs inaccessable when moving away from the tab.

For scrollbars do overflow: auto; in the CSS, why would ya want that in the menu though? Must be long list
