Hi,
I just released the new version (2.2) of Autosuggest control.
Here is the list of changes:
1. Item templates (see: http://www.prototypejs.org/api/template)
2. SuggestionItem inheritance
3. Some JS optimizations

See demo here: http://convincingmail.com/autosuggest-autocomplete.aspx
Download from here: http://convincingemail.com/Download.aspx

You can find more info & examples in the demo project.

Please ask your questions here or via support form http://convincingemail.com/Support.aspx we are always ready to help ;)

Thanks
