Navigation views are implemented as custom categories. Thus customizing navigation views is handled the same as customizing a custom category. For more information, see Guideline: Customizing a Custom Category. Keep in mind that the presentation name of a custom category that is a navigation view is the name that is displayed on the tab in the published method. In addition, the names of sub-custom categories in custom categories that are navigation views will be the names of the folders that are displayed in the navigation views that are published.
