Draggable Widget Menu and finding location on screen.

Hey All,
I have been trying to make a menu for my game that will allow players to drag and drop spawned nodes onto a bar in order to time functions. I have managed to setup all of the function related parts but I have no clue where to go with it. The nodes need to be able to be spawned and then moved to a location on the bar which I would then be able to translate to a percentage and then, using logic from that node/its corresponding actor, into a time frame to then run the function (I’ve figured out the math but have no way to get the variables nor spawn and move the nodes). I’m still new to UEBP so I’m sorry if this sounds dumb but any help would be greatly appreciated.

To any who require something similar:
