3 is the original menu, when trying to book it as example (Chapter 5 of the first four examples), then with infinite recursion into a first-class document prepared xml 

  Some plans are: 

  Core code: 

  Function addMenu (mc) ( 
  RemoveMenu ((mc.level-1) * depthDis (mc.level menuLevel-1) * depthDis-1); 
  Var tempArray = []; 
  TempArray = mc.data; 
  Var j = tempArray.length; 
  For (var i = 0; i <j; i) ( 
  Var d = mc.level * depthDis-i-1; 
  Var t = menu.duplicateMovieClip (the "menu" d, d); 
  MenuStyle (t, tempArray [i]. Attributes.text); 
  T._x = mc._x (mc._width dis); 
  T._y = mc._y (hei dis) * i; 
  If (tempArray [i]. ChildNodes [0]! = Undefined) ( 
  Var tmc = t.createEmptyMovieClip ( "nex", 2); 
  CreateNext (tmc, wid-12, 5); 
  ) 
  T.data [i] = tempArray. ChildNodes; 
  Mc.level t.level = 1; 
  T.id = i; 
  T.onRollOver = function () ( 
  AddMenu (this); 
  Mc.prev = mc.curr; 
  MenuOutStyle (mc.prev); 
  Mc.curr = this; 
  MenuRollStyle (mc.curr); 
  ); 
  If ([0] == t.data undefined) ( 
  T.onRelease = function () ( 
  Var _u = tempArray [this.id]. Attributes.link; 
  If (_u! = Undefined) ( 
  CreateLoading ( "swf /" _u); 
  ) 
  ); 
  ) 
  ) 
  ) 

  Uh, spent Tween category, the effect is very cool
