This is jsut th eloaded text, so I was wondering how to do the drop down menu

This is the basic code

var tnNr;
spacing = 10;
container._alpha = 0;
var curLength;
MovieClip.prototype.loadPic = function(pic, id) {
    info.text = "";
    this._alpha = 0;
    this.loadMovie(pic);
    temp = this._parent.createEmptyMovieClip("temp2", 998);
    temp.onEnterFrame = function() {
        var t = container.getBytesTotal(), l = container.getBytesLoaded();
        if (Math.round(l/t) == 1 && container._width != 0 && container._height != 0) {
            var w = container._width+spacing, h = container._height+spacing;
            border.resizeMe(w, h, id);
            
            delete this.onEnterFrame;
        }
    };
};
MovieClip.prototype.resizeMe = function(w, h, id) {
    var speed = 3;
    container._alpha = 0;
    this.onEnterFrame = function() {
        this._width += (w-this._width)/speed;
        this._height += (h-this._height)/speed;
        if (Math.abs(this._width-w)<1 && Math.abs(this._height-h)<1) {
            this._width = w;
            this._height = h;
            container._x = this._x-this._width/2+spacing/2;
            container._y = this._y-this._height/2+spacing/2;

            container._alpha += 5;
            if (container._alpha>90) {
                info.text = id;
                container._alpha = 100;
                delete this.onEnterFrame;
            }
        }
    };
};
