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).
