            var html = '';
            html += '<tr>';
            html += '<td><select name="item_ArtName[]" class="form-control item_ArtName" data-sub_category_id="' + count + '"><option value="">Select art</option><?php echo fill_select_box($connect); ?></select></td>';
            html += '<td><input name="item_Qty[]" class="form-control item_Qty" id="qty_2' + count + '" /></td>';
