   List Sub-Pages
   Versions prior to WordPress 2.0.1:

   Put this inside the the_post() section of the page.php template of your WordPress theme after the_content(), or put it in a copy of the page.php template that you use for pages that have sub-pages:

   <ul>
   	 '',
   		'child_of'    => $id,
   		'show_date'   => 'modified',
   		'date_format' => $date_format
   	) );
   	?>
   </ul>

   This example does not work with WordPress 2.0.1 or newer if placed in a page template because the global $id is not set. Use the following code instead.

   WordPress 2.0.1 or newer:

   NOTE: Requires an HTML list tag (either <ul> or <ol>) even if there are no subpages. Keep this in mind if you are using CSS to style the list.

   <ul>
   	 '',
   		'child_of'    => $post->ID,
   		'show_date'   => 'modified',
   		'date_format' => $date_format
   	) );
   	?>
   </ul>

   The following example will generate a list only if there are child pages (pages that designate the current page as a parent) for the current page:

   ID.'&echo;=0' );
   if ( $children) : ?>
   	<ul>
   		
   	</ul>

   Hiding or Changing the List Heading
   The default heading of the list (“Pages”) of Pages generated by wp_list_pages can be hidden by passing a null or empty value for the title_li parameter. The following example displays no heading text above the list.

   <ul>
    '' ) ); ?>
   </ul>

   In the following example, only Pages with IDs 9, 5, and 23 are included in the list and the heading text has been changed to the word “Poetry”, with a heading style of :

   <ul>
    array( 5, 9, 23 ),
   	'title_li' => '<h2>' . __('Poetry') . '</h2>'
   ) ); ?>
   </ul>

   List members of a custom post type
   If a given custom post type is hierarchical in nature, then wp_list_pages() can be used to list the member of that custom post type. In this example the custom post type Portfolio is listed:

   $args = array(
   	'post_type' => 'portfolio',
   	'title_li'  => __( 'Portfolio', 'textdomain' )
   );
   wp_list_pages( $args );

   I didn’t see anywhere that you could pass a sort_order argument. So I think it would be good to make it more obvious by including it in the args list.

   This code orders pages by post_date and sorts the pages by descending order so that you will get the latest pages first.

   wp_list_pages(array('sort_column' => 'post_date', 'sort_order' => 'desc'));

   List subpages even if on a subpage

   The above examples will only show the children from the parent page, but not when actually on a child page. This code will show the child pages, and only the child pages, when on a parent or on one of the children.

   This code will not work if placed after a widget block in the sidebar.

   post_parent ) {
   	$children = wp_list_pages( array(
   		'title_li' => '',
   		'child_of' => $post->post_parent,
   		'echo'     => 0
   	) );
   } else {
   	$children = wp_list_pages( array(
   		'title_li' => '',
   		'child_of' => $post->ID,
   		'echo'     => 0
   	) );
   }
   
   if ( $children ) : ?>
   	<ul>
   		
   	</ul>
   

   As an alternative, this code in a sidebar.php, displays only top level pages, but when viewing a page that has children (or is a child) it displays only children of that parent.

   When visiting main page, all top level pages are listed in the sidebar.
   When visiting a top level page with no children, all top level pages are listed.
   When visiting a top level page with children, just the children pages, and descendant pages, are listed.
   When visiting a child page, just the children, and descendant pages, of that parent, are listed.

   $output = wp_list_pages( array(
   	'echo'     => 0,
   	'depth'    => 1,
   	'title_li' => '<h2>' . __( 'Top Level Pages', 'textdomain' ) . '</h2>'
   ) );
   
   if ( is_page() ) {
   	$page = $post->ID;
   	if ( $post->post_parent ) {
   		$page = $post->post_parent;
   	}
   
   	$children = wp_list_pages( array(
   		'echo'     => 0,
   		'child_of' => $page,
   		'title_li' => ''
   	) );
   
   	if ( $children ) {
   		$output = wp_list_pages( array(
   			'echo' => 0,
   			'child_of' => $page,
   			'title_li' => '<h2>' . __( 'Child Pages', 'textdomain' ) . '</h2>'
   		) );
   	}
   }
   echo $output;

   Page list that only displays if child (sub) pages exist, displays page list of subpages on the parent page AND on the child pages
   However this code keeps the parent page name in the title which makes it different from the previous example.

   post_parent ) {
   	$children = wp_list_pages( array(
   		'title_li' => '',
   		'child_of' => $post->post_parent,
   		'echo'     => 0
   	) );
   	$title = get_the_title( $post->post_parent );
   } else {
   	$children = wp_list_pages( array(
   		'title_li' => '',
   		'child_of' => $post->ID,
   		'echo'     => 0
   	) );
   	$title = get_the_title( $post->ID );
   }
   
   if ( $children ) : ?>
   	<h2></h2>
   	<ul>
   		
   	</ul>

   Markup and styling of page items
   By default, wp_list_pages() generates a nested, unordered list of WordPress pages created with the Write > Page admin panel. You can remove the outermost item (li.pagenav) and list (ul) by setting the title_li parameter to an empty string.

   All list items (li) generated by wp_list_pages() are marked with the class page_item. When wp_list_pages() is called while displaying a page, the list item for that Page is given the additional class current_page_item.

   <li class="pagenav">
   Pages [title_li]
   	<ul>
   	<!-- Output starts here if 'title_li' parameter is empty -->
   		<li class="page-item-2 page_item current_page_ancestor current_page_parent">
   		[parent of the current Page]
   			<ul>
   				<li class="page-item-21 page_item current_page_item">
   					[the current Page]
   				</li>
   			</ul>
   		</li>
   		<li class="page-item-3 page_item">
   			[another Page]
   		</li>
   	</ul>
   </li>

   They can be styled with CSS selectors:
   [html]

   .pagenav { … } /* the outermost list item; contains whole list */
   .page-item-2 { … } /* item for Page ID 2 */
   .page_item { … } /* any Page item */
   .current_page_item { … } /* the current Page */
   .current_page_parent { … } /* parent of the current Page */
   .current_page_ancestor { … } /* any ancestor of the current Page */

   In order to achieve an accordion menu effect for instance, the following CSS can be used:

   .pagenav ul ul,
   .pagenav .current_page_item ul ul,
   .pagenav .current_page_ancestor ul ul,
   .pagenav .current_page_ancestor .current_page_item ul ul,
   .pagenav .current_page_ancestor .current_page_ancestor ul ul {
   display: none;
   }

   .pagenav .current_page_item ul,
   .pagenav .current_page_ancestor ul,
   .pagenav .current_page_ancestor .current_page_item ul,
   .pagenav .current_page_ancestor .current_page_ancestor ul,
   .pagenav .current_page_ancestor .current_page_ancestor .current_page_item ul,
   .pagenav .current_page_ancestor .current_page_ancestor .current_page_ancestor ul {
   display: block;
   }

   [/html]

   List all top-level pages and subpages only of this parent

   The following lists all top-level pages and

   if on a subpage – its siblings but not children of other top pages

   $ancestor_id = 1843; // you want to change this

   *Custom Post/Page Types*

   Custom page types will require the hierarchical property to be set to true in the register_post_type (see https://developer.wordpress.org/reference/functions/register_post_type/) parameter list.

   By default the only WordPress post type that is hierarchical is the ‘page’ type.

   Only hierarchical post types are returned by this function.

    List Pages by Page Order
    The following example lists the pages in the order defined by the Order setting for each page in the Pages→Edit panel.

    <ul>
    	 'menu_order' ) ); ?>
    </ul>

    If you wanted to sort the list by page order and display the word “Prose” as the list heading (in h2 style) on a sidebar, you could add the following code to the sidebar.php file:

    <ul>
    	' . __( 'Prose' ) . '</h2>' ); ?>
    </ul>

    Using the following piece of code, the pages will display without heading and in page order:

    <ul>
    	
    </ul>

    List parent page and all descendant pages

    Since there’s no way to tell wp_list_pages to display a particular parent tree (parent and all generations displayes) this example uses get_pages to get all the descendants for a parent, then use wp_list_pages to display the ‘family tree’.

     $parent );
    $pages  = get_pages( $args );
    
    if ( $pages ) {
    	$pageids = array();

    List current Page with its ancestors and children

    This example will list current page, ancestors of current page, and children of current page, Since child_of displays all children, wpdb is used instead, along with include to not display everything ‘and the kitchen sink’.

    // If the post has a parent.
    if( $post->post_parent ) {
    	// Collect ancestor pages.
    	$relations = get_post_ancestors( $post->ID );

    List topmost ancestor and its immediate children

    This method will show the topmost ancestor of the current page as well as the topmost ancestor’s immediate children. This can be used for clean secondary subnavigation.

    First, create the following function (preferably in functions.php, assuming this is for a theme):

    if ( ! function_exists( 'wpdocs_get_post_top_ancestor_id' ) ) {
    /**
     * Gets the id of the topmost ancestor of the current page.
     *
     * Returns the current page's id if there is no parent.
     * 
     * @return int ID of the top ancestor page.
     */
    function wpdocs_get_post_top_ancestor_id() {
    	if ( ! $post = get_post() ) {
    		return;
    	}
        
    	$top_ancestor = $post->ID;
        if ( $post->post_parent ) {
            $ancestors = array_reverse( get_post_ancestors( $post->ID ) );
            $top_ancestor = $ancestors[0];
        }
        
        return $top_ancestor;
    }
    } // Exists.

    Next, add the following code to your theme (wherever you want the menu to appear):

    <ul class="clearfix">
    	 '',
    		'include'  => wdocs_get_post_top_ancestor_id()
    	) );
    	
    	wp_list_pages( array(
    		'title_li' => '',
    		'depth'    => 1,
    		'child_of' => wpdocs_get_post_top_ancestor_id()
    	) );
