jquery autocomplete and formatItem / formatResult

Question

I am trying to hide some data from the autocomplete drop down. This is what I got:

$("#sVendor2").autocomplete("vendors2.cfm", {
 width: 300,
 selectFirst: false,
 autoFill: false
 });

Now, my vendors2.cfm page displays

#vendor_name# (#vendorID#), #vendorSiteCode# (#vendorSiteID#): #address#, #city#, #state#, #zip#|

What I want to do is the hide anything in parenthesis from the autocomplete drop down but still pass them to the next page. any help?
