Die javascripte dazu:

function collapseMenu(node) {
 if (!document.getElementById) return false;
 if (!document.getElementById("ajax")) return false;
 if (!node) node = document.getElementById("ajax");
 
 if (node.childNodes.length > 0) {
  for (var i=0; i<node.childNodes.length; i++) {
   var child = node.childNodes[i];
   if (child.nodeName == "UL") {
    child.style.display = "none";
   }
   collapseMenu(child);
  }		
 }
}

function prepareMenu() {
 if (!document.getElementById || !document.getElementsByTagName) return false;
 if (!document.getElementById("ajax")) return false;
 if (!ajax.getElementsByTagName("a")) return false;
 
var links = document.getElementById("ajax").getElementsByTagName("a");
 for (var i=0; i<links.length; i++) {	
  links[i].onclick = function() {
   toggleMenu(this.parentNode.getElementsByTagName("UL")[0], this.href);
   return false;
  }
 }
}

function toggleMenu(node, link) {
 if (!document.getElementById) return false;
 if (!link) return false;
 if (node.parentNode.parentNode.id == "ajax") {
 hideTopLevels();
 }
 if (!node) location.href = link.href;
 
 
 if (node.style.display == "") {
 Effect.Fade(node, {duration: 0.4});
} else {
 Effect.Appear(node, {duration: 0.3});
}
}

function addLoadEvent(func) {
 var oldonload = window.onload;
 if (typeof window.onload != 'function') {
  window.onload = func;
 } else {
  window.onload = function() {
   oldonload();
   func();
  }
 }
}

function hideTopLevels() {
 if (!document.getElementById) return false;
 if (!(node = document.getElementById("ajax"))) return false;
 
 if (node.childNodes.length > 0) {
  for (var i=0; i<node.childNodes.length; i++) {
   var child = node.childNodes[i];
   for(var j=0; j<child.childNodes.length; j++) {
    var grandchild = child.childNodes[j];
    if (grandchild.nodeName == "UL") {
     if (grandchild.style.display == '') {
      Effect.BlindUp(grandchild, {duration: 0.2});
     }
    }
   }
  }		
 }
}

addLoadEvent(collapseMenu);
addLoadEvent(prepareMenu);

Die nötigen .js files sind in der index.php im head eingebunden.

Zu finden ist das menü unter www.bebotta.net
