WP HTML5 Outliner (WPH5O) adds an HTML 5 outline plus a heading-level outline to the WordPress Toolbar.
<h4>Features</h4>
<ul>
<li>Matches the outlines provided by the <a href="https://validator.w3.org/#validate_by_uri+with_options" rel="nofollow ugc">W3C Markup Validation Service</a>. Caveat: In an HTML 5 outline, the W3C validator may hide some of the headings in an <code><hgroup></code> if any of them are empty. WPH5O will not. This difference is presentational, not structural.</li>
<li>Adds an ‘Outline’ node to the Toolbar. Outlines are displayed in a dropdown box, with the option to view them in a new browser window.</li>
<li>Runs only on pages or posts the user can edit. Administrators can view outlines for any page or post. Administration Screens are not outlined.</li>
</ul>

Outline to Mind Map lets you turn a plain text outline into a fully interactive, zoomable mind map — right inside your WordPress content.
I love mind maps and hope that this plugin will serve you well. I discovered <a href="https://markmap.js.org/" rel="nofollow ugc">Markmap.js</a> and asked Claude.ai to help me build a plugin around it. It takes a universe to make a sandwich; structure supports spontaneity.
How it works:
Write a Markdown-style outline between the shortcode tags and the plugin renders it into a smooth, animated SVG mind map — with clickable nodes, zoom, and pan.
<pre><code>[outline-to-mind-map]
# My Topic
## Branch One
### Leaf
## Branch Two
[/outline-to-mind-map]
</code></pre>
Features:
<ul>
<li>Simple shortcode — works in any post, page, or widget</li>
<li>Interactive: zoom, pan, and click nodes to fold/unfold</li>
<li>Configurable fold depth, dimensions, and color schemes</li>
<li>Five built-in color palettes: Default, Cool, Warm, Forest, Mono</li>
<li>Output caching via WordPress transients (Redis/Memcached compatible)</li>
<li>Settings page with full parameter reference</li>
<li>Dark mode aware</li>
<li>No account or API key required</li>
<li>Powered by the open-source <a href="https://markmap.js.org/" rel="nofollow ugc">Markmap.js</a> library</li>
</ul>
<h3>Usage</h3>
Basic example:
<pre><code>[outline-to-mind-map]
# My Project
## Planning
### Goals

With options:
<pre><code>[outline-to-mind-map fold="2" color_scheme="forest" height="600px"]
# My Topic

## Branch B
[/outline-to-mind-map]<h3>Shortcode Parameters</h3>

All parameters can be set globally at Settings → Outline to Mind Map and overridden per shortcode.
