Display Combo Boxes

Question

Im building a program that queries a database for options and displays the options in a number of comboBoxes. The comboBoxes are dynamically built and loaded via code and added to the stage. I would like to build the comboBoxes into a single movie clip (maybe not the correct wording)  so I can use options like tweening and such to make it look better. The code is below. Any suggestions are welcomed...
ps. the QueryDriver class is the class that provides the methods to load the comboBoxes.

Yes, that is the way to do it, just don't forget to addChild the mclip as well... here's a quick example using the built-in Tween class...
import fl.transitions.Tween;
var mclip:MovieClip = new MovieClip();
mclip.addChild(aComboBox)
mclip.addChild(aComboBox2)
mclip.addChild(aComboBox3)
addChild(mclip);
var tw:Tween = new Tween(mclip, "x", null, mclip.x, mclip.x+200, 1, true);
