I am looking for a JavaScript method or a framework to achieve this:
So in concrete words I like to have a tree structure same like the one in the Windows Explorer (where you can expand and collapse nodes) and on the right side you should be able to relate nodes to each others.
Building the tree structure is pretty simple, but displaying the relation for the nodes is quite tricky and honestly I don't know how to start.
I tried with various frameworks, but none that I know of has this build in functionallity. Unfortunately I cannot copy any code to JSFiddle...
