How to integrate a Drag & Drop?

Anybody that can help me with drag picture and drop it on relevant text slot?
I have seen a lot of drag and drop tutorials which works fine but not the way i need.
I dont know how to structure my code and nodes.

Here’s a small demo that shows how to implement a drag and drop system godot-demo-projects/gui/drag_and_drop at master · godotengine/godot-demo-projects · GitHub
