Dragging GameObjects to scene from canvas

Hey!

As title says... Canvas acts as inventory. I want to be able to drag gameobjects to the scene from canvas.
What should I put to the canvas? Images? GameObjects? and how an earth I can drag them from canvas to scene as gameobjects.

 

You'll probably want Images in your Canvas, but at some point during the drag, you have to convert those to real GameObjects.

You could do that as soon as the drag starts, or do it at the end on mouse-up, or do it when the dragged image leaves the canvas bounds. Whatever makes sense to you.
