To change the existing Navigation Menu, go to Admin > Templates and then Navigation section. Then click on the desired navigation item to change the name or add a new section.
Use the Drag and Drop method in order to change the navigation items and the order of their appearance. Once a menu item has been moved, a pop-up message, 'Success updating sort-order', will appear to the right of the 'Reload Page' option.
*Note that the name given to modules, features and information items may vary in your platform as they can be customized by Main Admin users.
