3.8 Cascading, List-Driven Items

Apps often need end-users to pick one or more choices from a list of valid options, and sometimes the available items depend on a previous selection the user makes.

For example, after picking a particular department the user might need to select an employee in that department. Oracle APEX makes list-driven page items easy to configure. It offers many different ways to visualize and select options, and simplifies defining cascading lists.

• List-Driven Items Available
  Your pages can use ten different kinds of list-driven items.
• Defining the List of Values
  When you create a list-driven page item, you define its list of valid choices either locally on the page item itself or by referencing a shared component List of Values by name.
• Configuring Cascading Lists
  When you need one page item's value to influence the list of choices in another list-driven item, you can easily configure this cascading effect.
