    delay: 0,
    source: function(request, response) {
        $.ajax({
            url: 'index.php?route=catalog/attribute/autocomplete&token=',
            type: 'POST',
            dataType: 'json',
            data: 'filter_name=' +  encodeURIComponent(request.term),
            success: function(data) {   
                response($.map(data, function(item) {
                    return {
                        category: item.attribute_group,
                        label: item.name,
                        value: item.attribute_id
                    }
                }));
            }
        });
    }, 
    select: function(event, ui) {
        $('input[name=\'product_attribute[' + attribute_row + '][name]\']').attr('value', ui.item.label);
        $('input[name=\'product_attribute[' + attribute_row + '][attribute_id]\']').attr('value', ui.item.value);

        return false;
    }
});
