How to use jQuery's formatItem with autocomplete?

[BaseballGraphs]

Hello,

I am trying to format the output of my data with the autocomplete function from jQuery. So far, I've been able to build the entire process, however, I want to limit the information I show in the autocomplete, but I still want the autocomplete to search through the entire string to find possible matches.

I understand that the formatItem function used in conjunction with the autocomplete from jQuery can accomplish this.

To give you some background here is the entire sequence of my code:

 $sql = ( 'SELECT cr, title, author, content, id FROM da_labels' );
  $result = mysql_query( $sql );
  $Response = array();
  while( $row = mysql_fetch_object( $result ) ){
       $Response[] = array(
                          "id" => $row->id,
                          "name" => $row->cr . ": " . $row->title . ": " . $row->content,
                         );
      }

The above is the php I use to select the data for the autocomplete to look up. The problem is that the data associated with 'content' is enormously large and I would prefer that it did not show in the autocomplete suggestions, but I still would like the autocomplete to look at it in order to come up with a suggestion.

<script>
      var AllCRData = <?= json_encode ( $Response ); ?>;
      var CRs = [];

      for(var i in AllCRData){
         CRs.push(AllCRData[i].name);
      }

      function getIdFromCR(_name){
          for(var i in AllCRData){
              if(_name == AllCRData[i].name){
                  return AllCRData[i].id;
              }
          }
      }

  $(document).ready(function(){
         $("#Responses").autocomplete({
             source: CRs,
              select: function(e, ui){
                 $("#hidden_cr").val( getIdFromCR($("#Responses").val()) );
              }});
     });
</script>

The above is the javascript I'm using to populate the autocomplete. I believe that the formatItem function would appear somewhere in the final portion of the javascript, but I am not sure how to implement it for my purposes.

I would like to format my autocomplete, so that it only shows $row->cr and $row->title from the php above, while hiding the $row->content, yet, still searching through the 'content' in order to find the most appropriate option.

I would really appreciate your assistance on how to implement the formatItem function for the autocomplete for jQuery.

Thanks!
