Yes, you do have the ability to delete your site map pages or sub-pages. You can hover over the Sitemap page or sub-page until the delete icon displays. However, please note the following BEFORE clicking the delete button.
Important Notes
Deleting a site map Page with Sub-Pages nested under it will cause every page in the structure to be deleted. For example, if your Page is 'Travel' with sub-pages in your site map for 'Registration', 'Teams', and 'FAQs', then all of these pages will also be deleted if you delete the top 'Travel' option.
Deleting anything on your site map will delete all articles, links, AND files uploaded directly on that page.
Deleting anything on your site map will not automatically make any navigation or intra-linked areas also delete.
Tip: If you're unsure if you're ready to delete a sitemap page, first try to set the Page or Sub-Pages to 'Pending Public View' mode.
