Updating your NavBar across all pages

As described above, if you have the Site navigation bar option turned on for a NavBar, then all changes that you make to the bar on one page are automatically applied to all the other pages too, including the location of the bar on the page.

However if you don't have that option turned on, set the navigation bar object to be a repeating object (right click and choose "Repeating object" > "Repeat on all pages") that appears on every page and all changes you make to any instance of the object automatically update on all pages.

See Repeating objects for more information.
