Copy selected nodes to a new tree

Question

I'm trying to copy all selected nodes from one fancytree control to another one on the same page. So far I've tried the following code but the second tree remains blank:

        var sourceTree= $("#tree").fancytree("getTree");
        var destinationTree= $("#destinationTree").fancytree("getTree");

        var selectedNodes = sourceTree.getSelectedNodes();
        var rootNode = destinationTree.rootNode;

        rootNode.addChildren(selectedNodes);

Any ideas?

Thanks

addChildren expects a plain object, so you could try

$.each(sourceTree.getSelectedNodes(), function(idx, node){
    destinationTree.rootNode.addNode(node.toDict());
});

or

$.each(sourceTree.getSelectedNodes(), function(idx, node){
    node.copyTo(destinationTree.rootNode);
});
