	// you can also add additional onLoad functions after the initial startList();
	// ex. add MM_preloadImages(); this will avoid the error of the drop down not working
}
// to add a second drop down menu you'll need another instance of the above funtion startList(), but you need to call it a different name, ex. funtion startList2(). You will also need to give it a unique ID, ex. navRoot = document.getElementById("navList2");
