GridFieldConfig_RelationEditor select by checkbox?

I've created a number of Gridfields with GridFieldConfig_RelationEditor for some many_many relationships.

The way this works is not ideal as the user must know what has already been added to be able to search for it.

Is there a way to achieve similar to what we used be able to do with the Dataobjectmanager. ie displaying every item and allow them to select the ones they want with a checkbox?


class Activity extends DataObject{
   public static $db = array(
      'Title' => 'Varchar(255)',
      'Summary' => 'Text'
   static $belongs_many_many = array(
      'TourPages' => 'TourPage'
   public static $summary_fields = array(
      'Title' => 'Title'
   public function getCMSFields_forPopup() {
       return new FieldList(
          new TextField('Title', 'Title'),
          new TextareaField('Summary', 'Brief Summary')


static $many_many = array(
   'Activities' => 'Activity'

$gridField = new GridField("Activities", "Activities", $this->Activities(), new GridFieldConfig_RelationEditor);
$fields->addFieldToTab("Root.Activities", $gridField);

+1 to the question.

I want to solve this problem as well.

This is just one of a few issues I am having with GridFields. The documentation is hugely lacking at the moment and it seems quite buggy.

When you add a new item or edit an existing one, why can you not return directly to the GridField? It is an annoyance for the user to have to come all the way out and go back in each time they want to add or edit something?

Randomly, when a new item is added, or an existing one edited and you click in the crumbtrail to get back to the page, 2 throbbers appear followed by a blank grey screen, requiring a refresh before any further action can be taken.

We are also experiencing random "Request-URI too large" errors when searching for items in the RelationEditor.

It's a pretty horrible experience handing this over to clients in this state.

I miss DataObjectManager.
