Help needed to rewrite code so main menus move down to make way for subs

Question

Can anybody please help me (slightly) alter some code.
I am working on a vertical menu with sub's and need to alter the AS so that when a sub menu is selected, the main menus below it move down to accommodate the new sub menu.
This is the code I am currently using is
GenerateMenu = function(container, name, x, y, depth, node_xml) {
    // variable declarations
    var curr_node;
    var curr_item;
    var curr_menu = container.createEmptyMovieClip(name, depth);
    // for all items or XML nodes (items and menus)
    // within this node_xml passed for this menu
    for (var i=0; i<node_xml.childNodes.length; i++) {
        // movieclip for each menu item
        curr_item = curr_menu.attachMovie("menuitem","item"+i+"_mc", i);
        curr_item._x = x;
        curr_item._y = y + i*curr_item._height;
        curr_item.trackAsMenu = true;
        // item properties assigned from XML
        curr_node = node_xml.childNodes[i];
        curr_item.action = curr_node.attributes.action;
        curr_item.variables = curr_node.attributes.variables;
        curr_item.name.text = curr_node.attributes.name;
        // item submenu behavior for rollover event
        if (node_xml.childNodes[i].nodeName == "menu"){
            // open a submenu
            curr_item.node_xml = curr_node;
            curr_item.onRollOver = curr_item.onDragOver = function(){
                var x = this._x + this._width -76;
                var y = this._y + 55;
                GenerateMenu(curr_menu, "submenu_mc", x, y, 10, this.node_xml);
                // show a hover color
                var col = new Color(this.background);
                col.setRGB(0xf4faff);
        }else{ // nodeName == "item"
            curr_item.arrow._visible = false;
            // close existing submenu
        curr_item.onRollOut = curr_item.onDragOut = function(){
            // restore color
            var col = new Color(this.background);
            col.setTransform({ra:100,rb:0,ga:100,gb:0,ba:100,bb:0});
        // any item, menu opening or not can have actions
        curr_item.onRelease = function(){
            Actions[this.action](this.variables);
            CloseSubmenus();
    } // end for loop
// create the main menu, this will be constantly visible
CreateMainMenu = function(x, y, depth, menu_xml){
    // generate a menu list
    GenerateMenu(this, "mainmenu_mc", x, y, depth, menu_xml.firstChild);
    // close only submenus if visible durring a mouseup
    // this main menu (mainmenu_mc) will remain
    mainmenu_mc.onMouseUp = function(){
        if (mainmenu_mc.submenu_mc && !mainmenu_mc.hitTest(_root._xmouse, _root._ymouse, true)){
            CloseSubmenus();
// closes all submenus by removing the submenu_mc
// in the main menu (if it exists)
CloseSubmenus = function(){
    mainmenu_mc.submenu_mc.removeMovieClip();
// This actions object handles methods for actions
// defined by the XML called when a menu item is pressed
Actions = Object();
Actions.gotoURL = function(urlVar){
    getURL(urlVar, "_blank");
Actions.message = function(msg){
    message_txt.text = msg;
Actions.newMenu = function(menuxml){
    menu_xml.load(menuxml);
// load XML, when done, run CreateMainMenu to interpret it
menu_xml = new XML();
menu_xml.ignoreWhite = true;
menu_xml.onLoad = function(ok){
    // create main menu after successful loading of XML
    if (ok){
        CreateMainMenu(10, 10, 0, this);
        message_txt.text = "message area";
    }else{
        message_txt.text = "error:  XML not successfully loaded";
// load first XML menu
menu_xml.load("menu1.xml");
Any help/feed back - even if its just to tell me Im asking for too much, would be incredibly appriciated.

onclipevent(load)                                           
total=_root.getbytestotal();                             
onclipevent(enterframe)
loaded=_root.getbytesloaded();
current=int(loaded/total*100);
p=""+current+"%";
if(loaded==total)
gotoandplay("Scene 2",1);
sorry for getting the code and coment mixed up.
