I want to hide elements of a form from users untill they click on a radio button. Any pointers?

Thanks in advance - K

radio_button_tag - since it is not associated with a model

Thanks -K

This is what Ihave tried - still not working:

in .rhtml (a partial)

              <%= radio_button_tag 'save',1, checked = false, options = {:onclick => 'show_hidden_div'} %>               <label for="saved_name" >Save To My Modules:</label>

            <div id = "save_module", style="display:none;">               <label for="saved_name" >Save As:</label>               <%= text_field 'mod', 'saved_name' %>             </div>

In application.js:

function show_hidden_div(){   if (document.getElementById) {    var save = form.save;    if (save[0].checked) {      document.getElementById("save_module").style.display = "block";    }   } }

I got it to work - thanks :slight_smile:
