I have built an App using jsTreeR where the tree structure the user creates is reflected in a mirror dataframe, and that dataframe then drives a series of mathematical operations. The user can create very elaborate trees with multiple branches. It would be helpful if the user could download or "save" a tree, naming each saved tree; and later upload or retrieve a tree to continue working on it or to simply activate that tree in order to run that mathematical operation. I could see a user needing a "library" of trees. Does jsTreeR have this capability? Are there any examples of this having been done?
I'm open to any suggestions. The image gives an example of "saving a tree"
