Lists
As the name implies, a
list
is a structure that APEX uses to keep a collection of data for links. The list structure allows
menus to be displayed consistently across numerous application pages, with easy maintenance in the Shared
Components area of an application. Don't confuse navigation lists with lists of values (LOVs). Lists are a navigational
structure with built-in templates for displaying information in different ways. LOVs are used to support data entry,
limiting the options a user can enter.
List templates have a lot of capability. They support hierarchical lists, graphical bullets, dynamic HTML, and
highlighting for the current page. Lists can contain data in a parent-child relationship; some list templates are
specifically designed to display parent-child data. APEX standard themes contain varying templates available for lists,
but if the behavior you're looking for isn't already available, it's possible to modify or create your own list template to
display and behave as desired.
The Help Desk application needs some lists to help users navigate to some key features. You're going to create
entries in the list for pages that don't exist yet, but you'll create those pages in the next few chapters. Here's the process
to follow:
1.
Navigate to the
Shared Components
section for your application.
2.
Locate and click the
Lists
entry under
Navigation

No lists currently exist. Click the
