Supplyist TOC Block

Description

Add the Table of Contents Block anywhere in your Gutenberg editor. It scans H2–H6 headings in the post content and builds a nested, clickable table of contents. Links automatically work by adding IDs to headings.

No configuration needed. Works on single posts and pages (not archives or category listings).

• No theme editing required
  You can activate the plugin on any site.
• Compatible with Gutenberg / Classic Editor
  It processes the final rendered HTML.
• SEO-friendly
  IDs are based on sanitize_title(), the same function WP uses for slugs.
• Works with headings that already have IDs
  It does not overwrite existing IDs.

Example:
– Structure Your Content – Write your post or page using semantic headings (H2, H3, etc.)—just like you normally would.
– Insert the Table of Contents Block – Add the « Table of Contents Block » anywhere in your editor (e.g., right after the introduction).
– Let It Work Automatically – The plugin scans your headings, builds a hierarchical, scroll-linked table of contents in real time, and updates dynamically as you edit.
