Multi drag support

[alexreardon]

Support the dragging of multiple Draggables. There are still a lot of open questions about this one.

• Currently the library has no concept of selecting a Draggable. What would this look like to support 'select' - is this handled by the library - or is it a pattern?
• What is the expected visual experience for a multi drag
• What would the api for onDragStart and onDragEnd look like?

We will be starting work on this soon 💖

Excited to see this is on the radar! Have you seen Google drive's multi drag interactions? I really love how they feel native when using them.

Maybe react-beautiful-dnd could provide some extra methods/components to achieve something similar? It would be awesome to somehow grab a bunch of nodes and have them animate towards the cursor.

This has landed :) #383

Can we have a documentation to use this feature?

Has anyone had any joy with getting this to work in react functional components (no typescript)?
