Autocomplete label not displaying data on hidden Element

Autocomplete label not displaying data on hidden input field with display:none Attribute after showing.

I am trying to autocomplete data from MySQL database with the below-given script. It is not displaying label while it is giving correct response in developer tool network console. When I show the div with the .show() method, the autocomplete not displaying label .

    function openSearchDiv(){
        $('.search').show();  
    }

$(document).on('focus','#search',function(){
$(this).autocomplete({
            source: function( request, response ) {
                $.ajax({
                    url: 'products.php',
                    dataType: 'json',
                    method: 'post',
                    data: {
                        name_startsWith: request.term,
                        type: 'type'
                    },
                    success: function( data ) {
                        response( $.map( data, function( item ) {
                                return {
                                    label: item['id'],
                                    value: item['id'],
                                    data : item
                                }
                            }));
                        }
                    });
            },
            autoFocus: true,            
            minLength: 1,
            select: function( event, ui ) {
               // $('#player').val(ui.item.data.player);
               // $('#marks').val(ui.item.data.marks);
            }               
        });
     });

.search {
      display:none;
      margin-top: 20px;
      } 

 <div class="search">
 <input type="text" id="search" placeholder="Type Id" />
 </div>

I have checked this code out of display:none attribute it's working perfectly
