Interface IReorderableListDropTarget

Can be implemented along with IReorderableListAdaptor when drop insertion or ordering is desired.

Remarks

This type of "drop" functionality can occur when the "drag" phase of the drag and drop operation was initiated elsewhere. For example, a custom IReorderableListAdaptor could insert entirely new items by dragging and dropping from the Unity "Project" window.
