Expand select dropdownlist

Question

I am trying to expand a open dropdownlist upon clicking on a statictext.
var w = new Window ("dialog");
var ss1 = w.add ("statictext", undefined, "Current Name: ", "alignment:left");
var g0 = w.add("group {orientation: 'row', alignChildren: ['fill', 'fill'], margins: 0}");
var lbCategoryCodes1 = g0.add("dropdownlist", undefined, ["test 1", "testerterg"]);
b = w.add('button', undefined, "OK");
ss1.addEventListener('mousedown', function(kev)
    var event = ScriptUI.events.createEvent('MouseEvent');
    event.initMouseEvent('mousedown', true, true, w);
    lbCategoryCodes1.dispatchEvent(event);
  },false/*==bubble*/);
w.show();
Does not work.
How do I?

withoutdix,
I hope, I understood you right.
Do you want to do something like this?
var w = new Window ("dialog");
var ss1 = w.add ("statictext", undefined, "Current Name: ", "alignment:left");
var lbCategoryCodes1 = w.add("dropdownlist", undefined, ["test 1", "testerterg"]);
lbCategoryCodes1.selection = 0;
var item = lbCategoryCodes1.selection;
b = w.add('button', undefined, "OK");
lbCategoryCodes1.onChange = function () {
    item = lbCategoryCodes1.selection;
    return item;
w.show();
try {
    alert(item);
catch (e) {}
Have fun
