The table of contents is a neat little box the shows up on the right hand side of the page content, that gives some internal links to sections in a page.
Table of contents example:
The table of contents works by using headers (H1 H2 H3) to make anchor points in the page.
Possible reasons Table of Contents not showing
- There are no headers on the page. Sometimes people accidentally use Bold instead of a header.
- Screen width is too small. If the screen width is too narrow (like on a mobile device) the table of contents will be hidden.
