    $.fn.openSelect = function()
    {
        return this.each(function(idx,domEl) {
            if (document.createEvent) {
                var event = document.createEvent("MouseEvents");
                event.initMouseEvent("mousedown", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
                domEl.dispatchEvent(event);
            } else if (element.fireEvent) {
