   3. Short Name - Specify the short name of this entry (referenced in the breadcrumb template).

   4. Long Name - Specify the long name of this entry (referenced in the breadcrumb template).

6. Under Target, specify the target location. The information that appears on the page depends on the branch type you selected:

   1. If the target location is a URL, specify the following:

      • Target is a - Select URL.

      • URL Target - Enter a URL. For example:

        http://www.yahoo.com
        

   2. If the target location is a page, specify the following:

      • Target is a - Select Page in this Application.

      • Page - Specify the target page number.

        You can also select reset pagination for this page. Selecting this option causes the page to return to the first set of data meeting a user's new query.

      • Request - Specify the request to be used.

      • Clear Cache - Specify the page numbers on which to clear cache.

   3. To set session state (that is, give a listed item a value):

      • With these values - Enter a comma-delimited list of values for the items your specified.

        You can specify static values or substitution syntax (for example, &APP_ITEM_NAME.). Note that item values passed to f?p= in the URL cannot contain a colon. Additionally, item values cannot contain commas unless you enclose the entire value in backslashes (for example, \1234,56\).

   4. Click Next.

7. To make the breadcrumb conditional:

   1. Make a selection from the Condition Type list.

8. Under Authorization, you can specify an authorization scheme.

   This authorization scheme must evaluate to TRUE in order for this component to be rendered or otherwise processed.

   Build options are predefined settings that determine whether components within an application are enabled.

10. When you are finished defining menu attributes, click Create at the top of the page.

Repeat these procedures for each breadcrumb entry you need to create.

Adding a Breadcrumb Region

A region is an area on a page that serves as a container for content. Once you create a breadcrumb and a breadcrumb template, the next step is to create a region. Once you create a region, you can add a breadcrumb to a page.

To create a breadcrumb region:

1. Navigate to the appropriate Page Definition. See "Accessing a Page Definition".

2. Under Regions, click the Create icon.

   The Create Region Wizard appears. Note that each wizard page displays a series of blocks on the left, representing the sequence of steps. The highlighted block indicates the step you are performing.

   1. Region Title - Enter a title for this region.

   2. Region Template - Select a region template.

      Regions are organized by position (or Display Point). To determine the appropriate region position, click the flashlight icon. A graphical representation appears.

   4. Sequence - Enter a number for the sequence.

   5. Click Next.

   1. Breadcrumb - Select the breadcrumb to be associated with this region.

   2. Breadcrumb Template - Select a template.

   2. Parent Entry - Select the appropriate hierarchical parent.

   3. Click Next.

Repeat these procedures for each page where you would like to add breadcrumb navigation.

About Creating Dynamic Breadcrumbs

To give users more exact context, you can include session state in breadcrumbs, making your breadcrumbs dynamic. For example, suppose a page in your application displays a list of orders for a particular company and you want to include the following breadcrumb:

Home > Orders > Orders for ACME Inc

In this example, ACME Inc not only indicates the page a user is on but also the navigation path. The Application Express engine stores the value of ACME Inc. in session state.

To create this type of dynamic menu, you must include a reference to a session state item in the breadcrumb's short name or long name. For example:

&COMPANY_NAME.
