Adding A Table of Contents (in the Content Editor)
The content editor includes a feature that automatically generates a hierarchical table of contents based on the headings in your content.
When you insert the table of contents, the editor looks at the headings your content uses, including their levels (Heading 2, Heading 3, and so on). Based on the heading levels, the editor creates links to the headings, indenting the links at similar levels.
To insert the table of contents, click Insert--> Table of Contents. While you're editing the content, the presence of the table of contents will appear as an icon >>.
In the saved or published version of the content, the icon will be replaced with a hierarchical list of links to headings in your content.
