This plugin is a Gutenberg block that takes a collection of posts organized by category (book name) and subcategories (chapter names) 
and creates a table of contents from them. You simply choose the root category to use, and the plugin does the rest. Once 
the table of contents is made, you can sort the chapters and posts, and the plugin will remember the order. The plugin also 
creates links to the next and previous posts.
<h3>Source Code</h3>
The Pau Table of Contents Block is a Gutenberg block created as recommended in the Block Editor Handbook 
(https://developer.wordpress.org/block-editor/). As recommended by the handbook, the source code is minified by the 
build process for production. In keeping with the spirit of open source, the unminified code 
for Pau Table of Contents is available at GitHub (https://github.com/paustian/pau-table-of-contents-block/).

Insert a widget or multiple widgets or a entire widget area (sidebar) into a page using a shortcode.
Set up your widget first in a normal sidebar. Check it works. 
THEN Drag your chosen widgets to the sidebar called “widgets for shortcode”.
Add the do_widget shortcode to the page where you would like the widget to appear (or the do_widget_area)
To use in the block editor, add a shortcode block, then type in (including the square brackets [do_widget widgetname] or copy the do_widget tip from the widget in the ‘Widgets for Shortcodes’ sidebar.
Please see detailed info on shortcodes and parameters under the installation tab (depending what the plugin directory developers have most recently done, this may be under the FAQ, or at the very least under the readme.)
Using a widget more than once?
Reference a specific widget instance from the do_widget shortcode, or the chosen sidebar from the do_widget_area shortcode. Eg: [do_widget id=widget-n]
For example: You could use the query posts widget in the page to create a archive within a page, or the rss widget to list feed content from other sites. For more details see <a href="http://webdesign.anmari.com/category/plugins/shortcode-any-widget/" rel="nofollow ugc">anmari.com</a>
The plugins default action is that it will magically find the settings for your themes sidebar and use the sidebar html to control the widgets output. In most cases this means the widget will be styled as per the rest of your theme. If that does not look good, parameters exist to try override this behaviour.
EG: in twenty-fourteen theme widget text ends up being white on white! widget_classes=none fixes that. Eg: [do_widget widget_classes=none yourwidget]
Changed your theme and worried about losing the sidebar settings ?
No problem, the plugin will save and restore the widgets_for_shortcode settings. On display it will then pick up the new themes sidebar settings.
Note:
PLEASE get your widgets working in a sidebar BEFORE activating this plugin, and please read https://wordpress.org/plugins/amr-shortcode-any-widget/installation/ and https://wordpress.org/plugins/amr-shortcode-any-widget/faq/ and/or see the settings page. To see a list of your widgets in their sidebars, add ?do_widget_debug to the page with the do_widget shortcode.

This tool works flawlessly. I was wondering about this kind of solution for a long. Thanks for creating this. I'll prepare a tutorial on it.
