Site editors can now insert collapsible text boxes into a new Google Site, which site viewers can click to expand. Collapsible text boxes can help condense large blocks of text, like content on FAQ or Help Center pages, allowing site viewers to quickly navigate to the most relevant information.

You can add a table of contents to help viewers navigate your page structure. The table of contents automatically updates when you edit your page. On your computer, open a site in new Google Sites. ... Important: Make sure your site has titles, headings, and subheadings which will be included in your table of contents.
