When configuring custom pagination, an option is available to display the secondary table of contents.
To activate the secondary table of contents, go through these steps:
- Select Add rule in the Pagination section.
- Select Configure rule.
- In the Pagination depth section of the Configure pagination drawer, select Custom pagination or Content-driven pagination.
- Select Split table of contents.
- Select Save.
- Select Save in the Reader page configuration menu.
When selected, the document's table of contents is split into two sections as follows:
- The document's chapters appear in the sidebar.
- The chapter's topics appear in the content pane. A selection of buttons let users navigate from one chapter to another and expand or collapse the chapter.
