I'm trying to add another opciĆ³n on the ticket form, just like the field 'user information', that shows another form to update the user information or add a new one. I was trying to do a 'copy paste' from this option, the form that I found was User-lookup.tmpl.php but I'm missing something else. Could you tell me which files should I look to do another similar option like 'user information'? Thank You.
