Accordion sliding menu

programming flash
1

Hi
I’ve build a very simple horizontal accordion-like sliding Menu.
It works except for the rollout after the release, then it slides back instead of staying in position.
The problem is that I need a slide back after the rollover on the rollout.
But I dont after the release.
In the end it should look like >>this<<.

function movItem(clip, speed, x) {
 clip.onEnterFrame = function() {
  var a = Math.abs(x-clip._x);
  clip._x += (Math.round(x-clip._x))/speed;
  if (a<=1) {
   clip._x = x;
   delete clip.onEnterFrame;
  }
 };
}
for (var i = 1; i<6; i++) {
 this["mc"+i].ID = i;
 this["mc"+i].onRollOver = function() {
  if (this.ID == 1) {
   movItem(mc1, 5, 30);
   movItem(mc2, 5, 60);
   movItem(mc3, 5, 90);
  }
  if (this.ID == 2) {
   movItem(mc2, 5, 60);
   movItem(mc3, 5, 90);
  }
  if (this.ID == 3) {
   movItem(mc3, 5, 90);
  }
 };
 this["mc"+i].onRollOut = function() {
  if (this.ID == 1) {
   movItem(mc1, 5, 0);
   movItem(mc2, 5, 30);
   movItem(mc3, 5, 60);
  }
  if (this.ID == 2) {
   movItem(mc2, 5, 30);
   movItem(mc3, 5, 60);
  }
  if (this.ID == 3) {
   movItem(mc3, 5, 60);
  }
 };
 this["mc"+i].onRelease = function() {
  if (this.ID == 1) {
   movItem(mc1, 5, 220);
   movItem(mc2, 5, 250);
   movItem(mc3, 5, 280);
  }
  if (this.ID == 2) {
   movItem(mc2, 5, 250);
   movItem(mc3, 5, 280);
  }
  if (this.ID == 3) {
   movItem(mc3, 5, 280);
  }
 };
}

Does somebody have suggestions about make it work like the example in the link or a better starting point to reach what I’m after?
