Support for drop targets instead of default sorting behavior

See original GitHub issue

Hi @clauderic! I am wondering if in your upcoming feature/collision-detection branch, there is going to be support for optionally overriding the sorting behavior?

In my use case, if a user drops an item in between others, it sorts the list but if the item is dropped on top of another, I can perform a different operation. So, to do this, I would need to know if an item is dropped on top of another (and not calculate new position in this case), or above or below the other (calculate new position in this case).

Let me know your thoughts!

I am too looking for something like this. @clauderic do you have any plans for supporting this feature? I can even try helping in PR for this change, I have very minimal POC working for this in my forked repo. Does collision_detection branch plan to handle this use case or is it something entirely different?

@clauderic @oyeanuj Guys, I have worked on something similar for my use case. It allows users to detect overlaps and act based on overlap detection. Now it passes three arguments to onSortEnd handler, oldIndex, newIndex and merge. merge would be true if there is a an overlap (configurable via mergeThreshold and swapThreshold). I have added few demos as well to the story book. Here are my changes, Please let me know if you guys want me send a PR.
