[jQuery] Autocomplete plugin - varying the ac_results class for different instances

[jQuery] Autocomplete plugin - varying the ac_results class for different instances


I've been using the jquery autocomplete plugin by Jorn Zaefferer
(thanks for the nice work).
My problem is that results are returned in a class="ac_results", and
I'd like to edit this class name at will with the initialization of
every instances so I can put them into different groups for styling
purposes.
I customized the styling of ac_results using the plugin's css file to
fit me needs, and that worked fine, because so far I needed only one
instance (or rather similarly-styled group of instances).
But now I need a second instance/group with different styling. If I
could specify the class name of the return results with
every .autocomplete initialization, that would solve my problem.
Problem is, I can't figure out if the plugin options permit this. At
one point early on when I started using the plugin, I thought I saw an
option like this, but now I can't find it.
Is this possible? Help much appreciated
