In sitetree.php I found how the metadata-thingy that is there is created. I suspect one can use it to create ones own. The next question is: How can one remove it? Anybody?

Thnx!

ToggleCompositeField::create('Metadata', _t('SiteTree.MetadataToggle', 'Metadata'),
						array(
							new TextField("MetaTitle", $this->fieldLabel('MetaTitle')),
							new TextareaField("MetaKeywords", $this->fieldLabel('MetaKeywords'), 1),
							new TextareaField("MetaDescription", $this->fieldLabel('MetaDescription')),
							new TextareaField("ExtraMeta",$this->fieldLabel('ExtraMeta'))
						)
					)->setHeadingLevel(4)

Well provided it plays nicely with the form API then you can just remove it like you do any other form fields on your page

class Page extends SiteTree {
..

function getCMSFields() {
$fields = parent::getCMSFields();
$fields->removeByName('Metadata');
}
}

Thanks!
