The Table of Contents (TOC) is a graphic support at the right side of the screen that provides orientation for the user when navigating and reading through the different pages. It highlights in black color which part of the TOC is just on display. In order to have the TOC properly functioning, editors need to follow the instructions below.
In order to let a TOC show the respective pages that have been created it is necessary to use the heading formats that are being offered by the Editor software. In a TOC only heading levels H2 and H3 are being shown, this means (level H1 is reserved for the page title only). There is a minimum of 5 H2 headings needed in order to show a TOC.
