Hi Chris,

Thank you, but I'm afraid this is not what I was looking for...

In my original message, I mentioned that this approach was what I tried
first. Then I realized that it was not very practical if later you want to
_re-enable_ that same option, in the exact position it occupied in the
options list. (It's not that it is very difficult, just that I would prefer
to avoid it.)

So I began to think about the 'disabled' attribute for the option element,
or a CSS property to hide the option (if that were possible). The problem is
that IE 5.x doesn't do anything when I write code like this:

<select>
<option disabled>first</option>
<option>second</option>
</select>

So, is there any hope to _disable_ an option, or is it necessary to _remove_
it?
