Yes, you do have the ability to delete your site map departments or sub-departments. You can hover over the site map department or sub-department until the red delete icon displays. However, please note the following BEFORE clicking the delete button.
Important Notes
Deleting a site map Department with Sub-Departments nested under it will cause every page in the structure to be deleted. For example, if your Department is 'Travel' with sub-departments 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.
If you're unsure if you're ready to delete a site map department, first try to set the Department or Sub-Departments to 'Pending Public View' mode.
