I need to provide a view of hierarchical data to the users who need the
ability to subsequently do the following:
(1) add additional nodes (root and non root nodes);
(2) arrange the nodes (drag and drop existing nodes to rearrange the tree)
(3) specify a short bit of text that will be displayed with each node.
After the user does all that, I need to then save it all to a database for
subsequent retrieval and manipulation in later sessions.
I'd appreciate any recommendations for controls that would provide much of
the functionality described.
Thanks!
