Hello,
I have an example of a widget that can be dragged around the screen as along as the mouse button is held down on it. I have included my blueprints via a notepad file. You can simply copy and paste them into their respective blueprints. This will give a good starting point. [MyCharacter_BP][1] and [YourWidget_BP][2] I hope this helps.

Make it a great day
