There is one option for the Sitemap Module : Site Map Properties
Sources
Select which menu(s) you'd like to extract links from to populate the site map. You can selectively choose menu(s) or select all menus.
Options
Set the number of columns to display, the number of sections per column, and alphabetize the section, and click 'Apply'.
This often requires a little trial and error to create an effective display.
Tips
- For long site maps, it is recommended to split them into multiple columns.
- Alphabetizing by section improves readability and navigability.
