Add a Table of Contents block to your posts and pages. The TOC is a nested list of links to all heading found in the post or page. To use it, simply add a block and search for “SimpleTOC” or just “TOC”. The maximum depth of the toc can be configured in in the blocks’ sidebar among many other options. There can hide the headline “Table of Contents” and add your own by using a normal heading block. Spin up a new WordPress instance with the SimpleTOC plugin already installed.
