How to create a Dynamic Tree when the depth and no. of nodes is unknown

Hello,

I am creating a SD Product Hierarchy using Web Dynpro Tree. The Requirement is : No of Nodes & the Depth of the hierarchy is unknown at design time. All the details are coming from the RFC.

So, How can I build a tree dynamically reflecting the dynamic depth & no.of nodes?. I have the "Creating WebDynpro Tree" tutorial with me, But unable to understand dynamic tree creation.

If somebody know how-to do it, Please let me know.

Thanks,

Sunita.
