Hello!
I’m making a drag and drop menu and i want to know - is it necessary to use HUD? Because we can Create Widget and Add it on Viewport without HUD.
I’n still learning! 
No need to use the HUD class. While it does have some unique functionality, it’s more for fringe case scenarios.
If you ever need a manager class to handle all the widgets in one place, you could use it as a communication hub since it’s easily accessible framework class reachable via the Player Controller.
One can make a full game without ever touching the HUD.
