You may want to add a global control to show or hide the breadcrumbs below the page title. This blog post explains how you can do that. Since users can always return to the home page of your app, by clicking on the Application title, it is OK to hide the breadcrumbs in some situations.
A Region can be set to be Customizable, but that affects only the current page.
You may want to give the users control to hide and show the Breadcrumbs when they don't need it, with a global switch. The control can be set by the online user via the Navigation Bar menu with the following method.
Add a Application Item
Name : APP_DISPLAY_BREADCRUMBS
Add an Application Computation
Computation Item : APP_DISPLAY_BREADCRUMBS
Computation Point : On New Instance
Computation Type : PL/SQL Expression
Computation : NVL(APEX_UTIL.GET_PREFERENCE(:OWNER || ':DISPLAY_BREADCRUMBS'), 'YES')
Add an Application Process
Name : Set Display Breadcrumbs
Sequence : 100
Process Point : On Load: Before Header
PL/SQL Code:
:APP_DISPLAY_BREADCRUMBS := case when :REQUEST = 'DISPLAY_BREADCRUMBS_ON' then 'YES' else 'NO' end;
APEX_UTIL.SET_PREFERENCE(:OWNER || ':DISPLAY_BREADCRUMBS', :APP_DISPLAY_BREADCRUMBS);
Condition Type : PL/SQL Expression
Expression 1 :
:REQUEST IN ('DISPLAY_BREADCRUMBS_ON','DISPLAY_BREADCRUMBS_OFF')
