Assisting end users while they are navigating the Siebel CRM user interface is an important task for developers.
The classic navigation utility is the drilldown, which can be defined as static, targeting the same view all the time, or dynamic, allowing for decision logic to be applied before selecting the target view for the drilldown.
Drilldowns are always displayed as hyperlinks to the end user and are tightly coupled with the thread bar. The thread bar content can be configured at the view level by defining the static and dynamic portions to display.
Toggle applets allow either manual or automatic selection of a replacement applet.
