Dropping Pieces Outside the Board

By default, pieces will return to their source square when dropped outside of the board. You can control this behavior with the dropOffBoard property:

"snapback" will cause pieces to animate back to their source square (this is the default)
"remove" will remove the piece from the board and trigger a position change
"donothing" will cause the piece to instantly disappear (and no position change)

Drag Events

Use the onDragStart, onDragMove, and onDrop events for more control over board behavior related to dragging pieces.
