To add in multiple columns to your collection_select drop-down, create a method in your Model to concatenate:
Model:
def last_name_and_fullname
"#{last_name}, #{full_name}"
end
View:
<%= collection_select :record, :individual_id, Individual.find(:all, 
rder => "last_name"), :id, :last_name_and_fullname, {:include_blank => true} %>
