This plugin adds the ability to put a tag in your page entry and have it display a list of pages. By deafult it will 
show the subpages of the page that it is on, but it will accept any of the options the 
<a href="https://codex.wordpress.org/Template_Tags/wp_list_pages" rel="nofollow ugc"><code>wp_list_pages</code></a> template tag 
will except <code>title_li</code> and <code>echo</code>. It is very simple to use, just put <code>[xls]</code> in the entry for your page where you want the list to appear.
There is one option in addition to the <code>wp_list_pages</code> ones. Specifying a <code>css_class</code> will override the default of 
 xls_list for the class of the surrounding <code>ul</code>.
It supports multiple uses of the tag with different options on one page.
Here are a few examples of valid tags:
<pre><code>[xls depth=2]
</code></pre>
Shows two levels of the subpages of the current page.
<pre><code>[xls child_of=10 exclude="13, 15, 33"]
</code></pre>
Shows all children of the page with id 10, excluding pages 13, 15, and 33.
<pre><code>[xls child_of="0" show_date="modified"]
</code></pre>
Shows all pages, and shows the last modified date of each page.
Check the <a href="https://codex.wordpress.org/Template_Tags/wp_list_pages" rel="nofollow ugc"><code>wp_list_pages</code></a> documentation for all of the possible options.

Xavin's List Subpages

I know it hasn't been updated for some time but I have been using it for many years and currently running it on WordPress 4.3.1 without any issues.
Such a simple yet useful concept and this plugin does it well. Listing the sub pages of a page inside itself in a bullet list with a shortcode.



Still the best list subpages plugin

Adds a tag that you can use in your pages to display a list of it's subpages.

Lets you disable automatic formatting like smart quotes and automatic paragraph creation, and use raw HTML/JS/CSS code in your posts without WordPress messing it up.
Features
With this plugin, you can wrap any part of your post in [raw]…[/raw] tags to prevent WordPress from converting newlines to HTML paragraphs, replacing apostrophes with typographic quotes and so on. This is very useful if you need to add a CSS block or JavaScript to your post.
RawHTML will also add new checkboxes to the “Edit Post” screen that let you disable certain WP filters on a per-post basis. This way you can:
<ul>
<li>Disable wptexturize (the function that creates smart quotes and other typographic characters).</li>
<li>Disable automatic paragraph creation.</li>
<li>Disable image smilies. </li>
<li>Disable convert_chars (the function that converts ampersands to HTML entities and “fixes” some Unicode characters).</li>
</ul>
The free version only supports editing posts in the Text tab (called “HTML” in older WordPress versions). <a href="http://rawhtmlpro.com/?utm_source=wordpress.org&utm_medium=readme_link&utm_campaign=RawHTML%20free" rel="nofollow ugc">Get the Pro version</a> if you want to be able to switch between Text and the Visual editor without WordPress messing up your content.
Compatibility
This plugin doesn’t fully support the Gutenberg editor. As of WordPress 5.0, some Raw HTML features will only work if you use the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> plugin.
Usage
To prevent a part of your post or page from being filtered by WordPress, switch to the Text/HTML editor and wrap it in <code>[raw]...[/raw]</code> or <code>...</code> tags. These two versions work exactly the same, except that the latter won’t be visible to your visitors even if you deactivate Raw HTML.
Example :
<pre><code>[raw]
This 

is 

a "test"!
[/raw]
</code></pre>
In this case, the tags will prevent WordPress from inserting paragraph breaks between “This”, “is” and “a “test””, as well as ensure that the double quotes arround “test” are not converted to typographic (curly) quotes.
To avoid problems, only edit posts that contain your custom code in Text/HTML mode. If you’d like to be able to also use the Visual editor, <a href="http://rawhtmlpro.com/?utm_source=wordpress.org&utm_medium=readme_link&utm_campaign=RawHTML%20free" rel="nofollow ugc">get the Pro version</a>. It will make the code betwen [raw] tags appear as a read-only placeholder when viewed in Visual mode, ensuring WordPress doesn’t change it.
Combining shortcodes
By default, shortcodes that are inside [raw] tags will not work. They will just show up as plain text. To enable shortcodes, add the <code>shortcodes=1</code> attribute to the tag:
<pre><code>[raw shortcodes=1]This [shortcode] will be run.[/raw]

[raw]This [shortcode] won't work.[/raw]
</code></pre>
Preserving <code>[raw]</code> code in excerpts
By default, the plugin will automatically remove any code that’s inside <code>[raw]...[/raw]</code> tags from post excerpts. You can prevent that by adding the following line to <code>wp-config.php</code>:
<pre><code>define('RAW_HTML_KEEP_RAW_IN_EXCERPTS', true);
</code></pre>
This will ensure that the plugin doesn’t strip <code>[raw]</code> blocks from automatically generated excerpts.
Notes
Some features of Raw HTML will only work for users who have the “unfiltered_html” capability. In a normal WordPress install that includes the Editor and Administrator roles. In a Multisite install, only the Super Admin has this capability by default.

Raw HTML

Simply works

Lets you use raw HTML or any other code in your posts. You can also disable smart quotes and other automatic formatting on a per-post basis.
