Hi there.

I am wanting to do related pages on my site. How I did this on 2.4 was use a related SiteTree object and TreeDropdownField. The code I'm using is bellow:

public static $has_one = array(

'Feature1Page' => 'SiteTree',
);

public function getCMSFields() {
$fields = parent::getCMSFields();

$fields->addFieldToTab('Root.Main', new TreeDropdownField('Feature1PageID', 'Feature 1 Link', 'SiteTree'));

$return $fields;
}

The dropdown menu shows in the CMS, but when I go to select something and press the arrow down button nothing is shown. Am I missing something or done something wrong? Or is this a bug that needs fixing in 3.0?

Cheers,
Steve

That looks like it should work to me. I am doing using the TreeDropdownField in a DatObject in 3.0.1 in the same way thaty ou are and it works fine for me.

Here is my code for reference...

class Feature extends DataObject {
   static $db = array (
      'Title' => 'Text',
   );

   static $has_one = array (
'HomePage' => 'HomePage',
'LinkPage' => 'SiteTree',
   );

public static $summary_fields = array(
'Title' => 'Title',
);

public function getCMSFields() {
return new FieldList(
new TextField('Title'),
new TreeDropdownField('LinkPageID', 'Link', 'SiteTree')
);
}
}

And in my template...

<% loop Features %>
   <a href="$LinkPage.Link" id="link$ID">$Title</a>
<% end_loop %>
