FancyTree Differentiate Between Dragging onto node and under a node

[codinglife456]

As mentioned in the title, is there any particular event currently available that differentiates between the dragging of a node onto another node vs under the node?

I want to create a custom validation such that users can only drag and drop a node under a node ( so that they will be on the same 'level' and they are not allowed to drop a node onto another where they will become a children of the node.
