Adding Breadcrumb Navigation

C.

The correct answer is A. navigation list, breadcrumb region, and breadcrumb entries.

Breadcrumb navigation is a user interface element that provides links to previously visited pages within a website or application, allowing users to easily navigate backward through the site hierarchy.

To add breadcrumb navigation to an existing application in Oracle Application Express 18, you need to follow these steps:

1. Add a Navigation List: The Navigation List is used to define the structure of the breadcrumb navigation. It contains the list of links that make up the breadcrumb trail. To add a Navigation List, go to the Shared Components section of the application and select Navigation Lists. Click on Create and select the type of Navigation List that you want to use.

2. Add a Breadcrumb Region: A Breadcrumb Region is a region on the page where the breadcrumb navigation will be displayed. To add a Breadcrumb Region, go to the page where you want to display the breadcrumb navigation and select the region type Breadcrumb. This will create a region on the page where the breadcrumb navigation will be displayed.

3. Add Breadcrumb Entries: Breadcrumb Entries are the links that make up the breadcrumb trail. To add Breadcrumb Entries, go to the Navigation List that you created in step 1 and add the links to the pages that you want to include in the breadcrumb trail.

Once you have completed these steps, the breadcrumb navigation will be displayed on the page, allowing users to easily navigate backward through the site hierarchy.
