drag gameobject from ui scroll panel to 3d space

What would be the best solution for dragging a 3d object that sits in a ui scroll view into a 3d space? my 3d objects will always live at a Z of 0 when they are out of the scroll panel and I already have functioning script for dragging. im just wondering how i could allow my 3d objects to be dragged out of a 2d toolbar and into my 3d game space. i was thinking i could render my 3d objects as images and then insert them at runtime into my scroll panel as needed. would that work? thanks for your time.
