At one point, I wanted to modify things on selectbox, like make some of it’s options inactive, modifying the different styles on the select options and so on. Luckily I found this site http://www.cult-f.net/2007/12/14/elselect/ on how to do it.
For instance I got a select box with options Yes, No, Maybe and wanted to disable Yes. You can do it like this
<select name=”sel”>
<option value=’yes’ disabled>Yes</option>
<option value=’no’ class=”cls1″>No</option>
<option value=’maybe’Â class=”cls2″>maybe</option>
</select>
