Create Site Map as content
When you create and publish the site map for your site, it is automatically available as an existing piece of content that you can place on a page.
The site map can be used as a menu on your site. The menu item labels are the page names, and each menu item links to the corresponding page if there is a published version of the page.
Typically, a site map menu is a secondary way for users to navigate a site.
There is no content editor for the Site Map content item. The pages included in the most recently published version of your site map appear in the Site Map content item.
