You should now see your Global Page listed in the pages for the application. Currently there is no content on the
Global Page. You use this Global Page to contain and display the breadcrumb region in the next section.
Breadcrumb Regions
Breadcrumbs are a popular navigation structure. They give the user a quick and intuitive representation of the current
navigation path with optional functionality to navigate back using the structure. Oracle Application Express uses the
structure in the builder shown in Figure

Example of breadcrumbs in the Application Builder
In APEX, breadcrumbs are a declarative structure with built-in behavior. They're managed as shared components
and have their own region type and template. When you ran the Create Application Wizard, the pages that the wizard
created automatically included a region to contain the breadcrumbs. Figure
5-39
shows the Breadcrumbs region in
Position 01 of the page.
