Procedure — Customize a Navigator
If required, there is a way to override default navigation behavior in the navigator. This can be achieved by implementing com.ptc.windchill.enterprise.navigation.NavigationListDelegate and providing a custom behavior. For example, there is a requirement that a particular first level navigation tab should show all the nodes instead of showing only recently accessed nodes.
The following section will illustrate an example of showing all the context nodes instead of default behavior of showing only recently accessed ones.
