I'd like my tree to open with a single root node - 'Subject Areas'. When the node is expanded, the subject ares will be shown. When a subject area is expanded, a node for 'Systems' might be displayed. When the Systems node is expanded, all of the systems would be displayed. Currently, my tree opens with a number of root nodes - each one representing a subject area. How do I force that 'Subject Area' header into the root node?
Thank you.

Hello Scott,
Thank you for your post. I have been looking into it and I created a sample project for you with the functionality you want. Basically I defined a hierarchical data structure and then I added an additional class for the RootNode. It has a string Property and an ObservableCollection of my actual data. Then I create a collection with one item of this type and set it as ItemsSource of the XamDataTree. This way the tree has the structure you want. Please let me know if you need further assistance on this matter.
Looking forward for your reply.
Impressive service. Thanks for getting back to me so quickly.
