Subpage Listing allows you to take full advantage of WordPress Pages’ hierarchy by generating a navigational tree of the pages below them (subpages).
For example, say you have a parent page called “Parent.” Now, say you have 3 pages under “Parent,” called “Child1,” “Child2,” and “Child3.” Now, say that you have 2 pages under “Child2” called “Grandchild1” and “Grandchild2.”
Subpage Listing would create a navigation tree for “Parent” that looks like this:
<ul>
<li>Child1</li>
<li>Child2
<ul>
<li>Grandchild1</li>
<li>Grandchild2</li>
</ul>
</li>
<li>Child3</li>
</ul>
This allows you to very easily create a complex hierarchical structure that can be browsed.
<h3>Advanced Usage</h3>
Blank pages will automatically be given a navigation tree. This allows you to quickly create “container” pages (all you do is fill in a title, and choose the page’s parent.)
If you would like to insert the navigational tree manually (that is, surrounded by text of your choosing), use the “Subpage Listing” quicktag that will show up on the Write Page screen (sorry, no RTE support at this time). This will insert the tag:  which will be replaced by the listing of the subpages.
Note: when inserting the tag manually, make sure that there is a blank line both above and below the tag, so as to ensure proper handling of your surrounding paragraphs by WordPress.
Version 0.6 was a massive update that added a bunch of new functionality. The ability to show the current page’s parent has been added, as well as the ability to show the current page’s siblings. You can also suppress the showing of children, and show only siblings, parents, or both. To use these features within a post, use this syntax:  The first “parameter” is the depth you want to show. You can set this to 0 to suppress display of children. The second “parameter” is a boolean switch for display of the parent page. The third “parameter” is a boolean switch for display of sibling pages. All are optional, although if you want to set the second “parameter”, you also have to set the first, and if you want to set the third, you have to set all three.
There is also a new function for use in your templates. Many people wanted to show subpages or siblings in their sidebar, so now you can do that. <code><?php txfx_wp_subpages(); ?></code> is the most basic form, but it can take many parameters.
<pre><code><?php txfx_wp_subpages(5, false, false, '<ul>', '</ul>', true); ?> will show 5 pages deep (first parameter), hide the parent (second parameter), hide the siblings (third parameter), wrap the whole thing in '<ul>' and '</ul>' (fourth and fifth parameters), and will echo the result (sixth parameter). These happen to be the default settings, that I have just illustrated.

Subpage Listing

The default custom menu in WordPress only allows checking the “Automatically add new top-level pages” (Appearance > Menus) or adding a Navigation block with all pages and all child pages (Appearance > Editor).
With Auto Submenu you get extra functionality to automatically include child pages into the menu.
NEW: ASM now provides support for the Customizer via Appearance > Customize 
NEW: ASM now provides support for Full Site Editing with the Gutenberg Block Editor via Appearance > Editor
<h3>Using it</h3>
Enable the plugin and go to Appearance > Editor.
For each Page in your menu, you now have the following extra configuration options:
<ul>
<li>Add child pages as submenu y/n; </li>
<li>child pages are ordered ascending by Menu Order;</li>
<li>specify the (maximum) nesting depth of children you want to show (max 3);</li>
<li>specify the title for the child pages. For this you can use %post_title, %post_author and other wildcards, see ‘Other Notes > Wildcards’. Default value: %post_title</li>
</ul>
Via Appearance > Menus and Appearance > Customize you also get the following option:
<ul>
<li>Check the “Automatically add new top-level and all its child pages to this menu (Auto Submenu)”-checkbox.</li>
<li>If this option is checked, all top-level pages will automatically be added and will automatically have all child pages added as submenu.</li>
</ul>
With the Free version you cannot control the nesting depth of the child pages, all subpages are added, regardless the depth of the page tree.
<h4>Wildcards</h4>
You can control the title of the menu items generated by the plug-in with the following wildcards:
<ul>
<li>%post_title</li>
<li>%post_author</li>
<li>%post_date for the unformatted post date: 2012-11-10 18:14:23</li>
<li>%post_date() for a formatted post date with the following default formatting: November 10th, 2012</li>
<li>%post_date(<your formatting here>) for custom date formatting. Example: %post_date(l jS \of F Y, h:i:s A). See <a href="https://codex.wordpress.org/Formatting_Date_and_Time" rel="nofollow ugc">https://codex.wordpress.org/Formatting_Date_and_Time</a> for formatting options.</li>
<li>%post_date_gmt</li>
<li>%post_date_gmt()</li>
<li>%post_date_gmt(<your formatting here>)</li>
</ul>

Auto Submenu

Good, saved me from a lot of work. Bookmarked



Perfect!

Dynamic menus: Add a page to your menu and then let WordPress automatically add the child pages.
