Tab navigation describes how the various UIM pages grouped as part of a tab can be navigated to within a tab. There are two elements to tab navigation; the Content Area Navigation Bar, and the Page Group Navigation Bar.
The navigation bar contains a number of tabs, each of which can map to a single UIM page or alternatively a set of UIM pages. The tabs in the navigation bar are referred to as navigation tabs. Refer to User Interface Element 8 of Tabs for an example of a navigation bar configured in an application.
Where a navigation tab maps to a set of UIM pages, these UIM pages are displayed as a page group navigation bar. Each link in the page group navigation bar is referred to as a navigation page. Refer to User Interface Element 16 of Tabs for an example of a page group navigation bar configured in an application.
Selecting a navigation tab or navigation page will result in displaying the relevant UIM page in the content area of the tab. For navigation tabs that have a page group navigation bar, the first navigation page in the page group navigation bar is selected when the navigation tab is selected.
If a user selects a subsequent navigation page and then changes to a different navigation tab, the selected navigation page is remembered when the user returns to the original navigation tab and the page is reloaded.
The tab navigation configuration is key to when new tabs are opened. It is used to determine what UIM page is associated with what tab. For more information on this consult Opening Tabs and Sections.
