Hi:
How does the new tabs in the CMS work? Can we have sub-tabs anymore ?
For example, If i have Gallerypage i will need the following tabs:
Content->
Gallery->Images
Gallery->Settings
Gallery->AdvancedSettings (With access limited to a member or group )
Settings -> ... & so on

Does sub-tabs work anymore ? if so, how do i get them working.
Thanks

I'd like some example also.

I'd like to know how to do a "drop tab" just like the metadata has! that way it could save space.

I have figured out how to add a tab

eg Info panel
extract

	$fields->addFieldToTab("Root.IntroPanel", 
		
		new HTMLEditorField('IntroPanelOne',
		_t('Page.ColumnOne','Panel1')
		)
		);

full

<?php
class Page extends SiteTree {

	public static $db = array(
	
		'topnav' => 'Boolean',//menu
		'IntroPanelOne' => 'HTMLText',
		'IntroPanelTwo' => 'HTMLText',
		'IntroPanelThree' => 'HTMLText'
	);

	public static $has_one = array(
	//'Page' => 'SiteTree'
	);
	
	
	static $defaults = array(
	'topnav' => 1
	);
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
	
		//menu
	$fields->addFieldToTab("Root.Main", 
			new CheckboxField(
			'topnav',
			 _t('Page.topnav', 'Tick to show on top nav')
			 ),
			 'Content'
	);
		
		
		$fields->addFieldToTab("Root.IntroPanel", 
		
		new HTMLEditorField('IntroPanelOne',
		_t('Page.ColumnOne','Panel1')
		)
		);
		
		
		$fields->addFieldToTab("Root.IntroPanel", 
		
		new HTMLEditorField('IntroPanelTwo',
		_t('Page.ColumnOne','Panel2')
		)
		);
		
		
		$fields->addFieldToTab("Root.IntroPanel", 
		
		new HTMLEditorField('IntroPanelThree',
		_t('Page.ColumnOne','Panel3')
		)
		);
		
				
		//Main
	
		
			return $fields;
		} //endgetCMSFields

The way to achieve the drop down like Matatags is like this.

$fields->addFieldToTab("Root.Main", new ToggleCompositeField('UniqueName', 'Section Name',
		array(
			new TextField('HeroTitle', 'Title'),
		)
	), 'Metadata');
