The attached document is intended to provide comprehensive information on the implementation of a traditional mutli-level breadcrumb tracking function as part of a ServiceNow Service Portal implementation instance.

That is, the ServiceNow Service Portal framework provides a core breadcrumb widget solution that does not support automatic multi-level navigation tracking. Instead, a great deal of widget customization is required, as well as event triggering for inter-widget communication; and even then navigation tracking is incomplete (e.g., simply determining the parent url is problematic).

Here, a single comprehensive breadcrumb navigation solution is presented. Moreover, the presented solution provides a simple, centralized mechanism for handling pages that may require special navigation/breadcrumb handling so that there remains only a single comprehensive solution for all portal pages.

Further, script include libraries that support additional Service Portal framework utility are included.

I hope the information proves useful to some.

Comments welcomed and appreciated.
