Changing Order to Top Navigation
Ordering the top navigation can be done when creating content or when updating the order.
When creating content:
Sort Order: Sort order is the order in which the links for the pages display in the menu at the top of the page. This is set alphabetically. For example, if the letter A is entered for New Page 1 and the letter B is entered for New Page 2, the display names for these new pages will display in the top menu as New Page 1, New Page 2.
