I’d do it like this: <select onchange=”jsFunction()”> <option value=”” disabled selected style=”display:none;”>Label</option> <option value=”1″>1</option> <option value=”2″>2</option> <option value=”3″>3</option> </select> If you want you could have the same label as the first option, which in this case is 1. Even better: put a label in there for the choices in the box.
