HierarchicalDataTemplate Skip Hierarchy

I have a data structure like

Level1

--Level2

----Level3

------Level4

shown in开发者_JS百科 a HierarchicalDataTemplate. This is so far ok, but i would like to skip Level 2 & 3, so that Level 4 is directly under Level 1. Is that even possible?

You should create new structure model and use Converter to convert from one structure to another.
