In the PHP you should set the "hidden" element as visible and the two new elements as hidden. Then after they're output just put in some quick script to make them visible. i.e. hidden ones should have style="visibility: hidden; display: none;". <script language="javascript"> document.getElementById("hiddenSelect").style.visibility = "hidden"; document.getElementById("hiddenSelect").style.display = "none"; document.getElementById("firstSelect").style.visibility = "visible"; document.getElementById("firstSelect").style.display = ""; document.getElementById("secondSelect").style.visibility = "visible"; document.getElementById("secondSelect").style.display = ""; </script> > > Laurent > > > Philippe Jausions wrote: > > > Laurent Laville wrote: > > > >> Laurent Laville (http://pear.php.net/user/farell) has commented on > >> the proposal for HTML::HTML_QuickForm_advmultiselect. > >> > >> Comment: > >> > >> Philippe, > >> > >> I think that non-js browsers (or js disabled) is a problem for all web > >> application.
