LuckyWP Table of Contents

It does what one expects it to do and offers tons of useful options if one wants to tweak something. Simply great!

Really nice


Tried many ToC plugins, this one is great because it looks clean, and correctly handles the default state whether it's opened or closed!


Great plugin!

This is a great plugin! Initially, I wasn't sure about installing a plugin that automatically installs table of contents on every posts, instead of selected the posts I want to show the TOC on. After using it, I came to the conclusion that:
1/ It's much better if you may uninstall the plugin, it won't require removing code from posts;
2/ The options ensure you will make TOC available on posts that realy need it. It's very well thought.

Creates SEO-friendly table of contents for your posts/pages. Works automatically or manually (via shortcode, Gutenberg block or widget).

Clearcode

<p>The WordPress CC-TOC plugin automatically creates a table of contents (TOC) for posts/pages (and/or custom post types) based on headings in content. This plugin can also output a listing of child pages (INDEX).</p>
<p>The TOC by default appears before, while the INDEX appears after the content post/page.</p>
<h4>Tips & Tricks</h4>
<ol>
<li>You can disable support for TOC and/or INDEX displaying in specific post/page edit page manually.</li>
<li>You can also use shortcode (by default <code>toc</code> and/or <code>index</code> – you can change it in the settings):<br />
[toc] and/or <code>[index]</code></li>
</ol>


CC-TOC

This plugin automatically creates a table of contents based on html headings in content.
