I took a look at the example on the Scriptaculous site and I'm still a
bit unclear. I'm already using the informal class, and it makes good
sense to use it again (with a display:none there) but I'm not sure how
I'll be able to retrieve that id number once the user selects it. Just
a bit more context around how you approached it (or maybe a peek at
the code you put together) would be wonderful.
Thanks,

There's a couple ways to do this. The auto completer values are an un-ordered
list, but they can have other stuff in there. You are allowed to have a tag of
class "informal" that is displayed, but not used as a value. So do something
like this
<ul>
<li>
<span class="id" style="display:none">1234</span>
<span class="informal">John Doe ([EMAIL PROTECTED])</span>
</li>
</ul>
See http://demo.script.aculo.us/ajax/autocompleter_customized for more details
and an example.
