I have attached 4 pictures.
Plan1, Plan2 - Creating diagrams and saving their nodes of diagram into the database.
GetPlan1, GetPlan2 - Retrieving saved nodes from the database and adding them to the diagram builder.
The idea is that the user can create any number of plans he wants. Let say, User created 5 plans of which 3 plans belong to Group1 and 2 belong to Group2.
I have vertical tabs of all the Groups available. On Click, The tab content should get the respective plan Overviews as shown in the paint file.
Hope the requirement is clear
