how to Drag and drop QFrame inside Qtreewidget

Hi there, I am beginner to intermediate level python programmer.

my question: How to move QFrame which contains multple QtWidgets, within QTreeWidget. Please see the example code below: Press the button to add childs and try dragging them in between other childs or the parent of the first level tree hierarchy, it will lose its data. I am very illiterate in using Mime Data or drag & drop events. The concept is that if a user selects "Repeat" it will open nested child with "Add & remove" buttons (which i will program later)
But my main goal as of right now is to make my qtreewidgetitems (Qfram) dragable.

Please see the code files Attachment 13541 Attachment 13542below:
