Thanks to everyone who installed this extension to hide pages from the SiteTree (almost 16.5K composer installs since 2012). Since comparable functionality has ben added to SilverStripe framework (Hierarchy), I'm not updating this module to SS4.

I've tagged a 2.0 release marking incompatibility from SS3.5 upwards (in composer), this should prompt users to migrate to core functionality as described below. I'll leave this repo as-is so please open a ticket if this causes any problems for you and I'll to my best to sort things out.

The 1.1 release should remain be usable on any SS3 version if needed, but I recommend simply uninstalling this module from SS3.5 onward and updating your config as follows instead:

Configuring hidden pages in SS3.5+

$hide_from_cms_tree hides in CMS, not in front-end

Hiding pagetypes in the CMS, in general

    - 'PageClassToHide'

Hiding pagetypes in the CMS, only if sub-page of a 'holder' pagetype

    - 'PageClassToHide'

$hide_from_hierarchy hides both in CMS & front-end

Hiding page types in both the CMS & Front-end, in general

    - 'PageClassToHide'

Hiding page types in both the CMS & Front-end, only if sub-page of a 'holder' pagetype

    - 'PageClassToHide'

Managing 'hidden' pages in SS3.5+

Manage hidden pages using a Gridfield (see: silverstripe-gridfieldsitetreebuttons) on the holder page or use a ModelAdmin or similar.

Of course there's also the very inspireding Lumberjack module (but you've probably seen that being plugged already)... (/sarcasm)

Getting 'hidden' pages in front-end

If using $hide_from_hierarchy, hidden pages will not be included in $Children loops. Instead, they can be queries using something like:

	public function HiddenChildren(){
		return SiteTree::get()->filter('ParentID', $this->ID)->sort('Sort');

Or, paginated:

	public function PaginatedChildren(){
		$children = SiteTree::get()->filter('ParentID', $this->ID);
		$ctrlr = Controller::curr();
		$children = new PaginatedList($children, $ctrlr->request);
		return $children;

Legacy: using excludechildren module (in SS<3.5)


  • SilverStripe 3.0 or newer (<3.5)


Hide SiteTree items from from the sitetree (and, with some extra code/modules, manage them from a GridField):


composer require micschk/silverstripe-excludechildren dev-master


In config.yml (best):

  classexists: 'ExcludeChildren'
	- 'ExcludeChildren'
	- 'SubPage'
	- 'AnotherPageType'
  # optionally exclude from theme $Children as well (set to true if desired, default only from CMS)
  # eg. to exclude pre-existing child pages with 'show in menus' = true
  force_exclusion_beyond_cms: false

Or in your Page class (php):

	class SubPageHolder extends Page {
		static $extensions = array("ExcludeChildren");
		static $excluded_children = array('SubPage', 'AnotherPageType_Extending_Page');

Or externally via _config.php:

		Object::add_extension("SubPageHolder", "ExcludeChildren");
		Config::inst()->update("SubPageHolder", "excluded_children", array("BlogEntry"));

###Then, add a GridField instead to create/edit subpages (See Gridfieldpages module below for a turnkey solution/example)

	$gridFieldConfig = GridFieldConfig::create()->addComponents(
		new GridFieldToolbarHeader(),
		new GridFieldAddNewSiteTreeItemButton('toolbar-header-right'), // GridfieldSitetreebuttons module
		new GridFieldSortableHeader(),
		new GridFieldFilterHeader(),
		$dataColumns = new GridFieldDataColumns(),
		new GridFieldPaginator(20),
		new GridFieldEditSiteTreeItemButton(), // GridfieldSitetreebuttons module
		new GridFieldOrderableRows() // Gridfieldextensions module, default 'Sort' is equal to page sort field...
		'Title' => 'Title',
		'URLSegment'=> 'URL',
		//'getStatus' => 'Status', // Implement getStatus() on child page class, see gridfieldpages module for an example
		'LastEdited' => 'Changed',
	// use gridfield as normal
	$gridField = new GridField(
		"SubPages", # Can be any name, field doesn't have to exist on model...
		"SubPages of this page", 
        SiteTree::get()->filter('ParentID', $this->ID),
    $fields->addFieldToTab("Root.SubPages", $gridField);

Looping over $Children in templates

This module only hides child pages from the CMS sitetree by default. So you can just use $Children as usual in your theme. Child pages will also be available when creating links to pages from the CMS editor.

When excluding pages from the front-end as well (force_exclusion_beyond_cms), you can add an alternative getter to your Holder:

	public function SortedChildren(){
		return SiteTree::get()->filter('ParentID', $this->ID)->sort('Sort');

Or, paginated:

	public function PaginatedChildren(){
		$children = SiteTree::get()->filter('ParentID', $this->ID);
		$ctrlr = Controller::curr();
		$children = new PaginatedList($children, $ctrlr->request);
		return $children;

Things to check if your pages are not showing up in $Children:

  • is force_exclusion_beyond_cms set to false (or use custom getter)?
  • are your child pages set to appear in menu's (show in menu's)?

Customising your children

If you need to customise your hidden children by more than just classname you can implement the getExcludedChildren which needs to return a DataList of the children to show in the SiteTree.

Pro tip

Add GridfieldSitetreebuttons to your gridfieldconfig to edit the pages in their regular edit forms:

Or use/subclass the preconfigured GridfieldPages module, which contains both excludechildren, sitetreebuttons, sorting and publication status:
