Animated xml menu

Hi all, i’ve got myself a little problem. I want to make an xml menu. That aint the problem, but i want it to be animated. So after the preloading of the swf, the menu needs to drop down, piling up the items. You can see an Example at and press “Press” (lol). On the left you see a Newsfeeder preloading and then dropping down while the boxes expand. I looked at every tutorial, googled 5 hours but coulndt find something remote. Only those “instant” showing menu.

I should make 1 Movieclip with a box expanding from small to big and put a stop in the end, and put a dynamic textarea in the lastframe of the movieclip, then load the xml and drop the boxes one by one. Check the site and you’ll understand.
It would be something like

menuXml = new XML();
	 menuXml.ignoreWhite = true;
	 setInterval(makeMenu, 500, ee);
	 menuXml.onLoad = function(success) {
 if (success) {
  menuItem = this.firstChild.childNodes;
  for (var i=0; i<menuItem.length; i++) {
	 item = _root.attachMovie("itemClip", "itemClip" + i, i);
	 item._x = 0;
		   for (var j = 0; j<20*i; j++) {
		   item._y += j
	 item.itemLabel.text = menuItem*;
	 item.myUrl = menuItem*.attributes.url;
	 item.onRelease = function() {
	 setInterval("MakeMenu", 200);

I dont know exactly what to do with the makemenu function. Is using the setinterval method the right and best thing to do or is something else easier?
