Outline to Mind Map

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 Markmap.js 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.

[outline-to-mind-map]
# My Topic
## Branch One
### Leaf
## Branch Two
[/outline-to-mind-map]

Features:

• Simple shortcode — works in any post, page, or widget
• Interactive: zoom, pan, and click nodes to fold/unfold
• Configurable fold depth, dimensions, and color schemes
• Five built-in color palettes: Default, Cool, Warm, Forest, Mono
• Output caching via WordPress transients (Redis/Memcached compatible)
• Settings page with full parameter reference
• Dark mode aware
• No account or API key required
• Powered by the open-source Markmap.js library

Usage

Basic example:

[outline-to-mind-map]
# My Project

With options:

[outline-to-mind-map fold="2" color_scheme="forest" height="600px"]
# My Topic

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