Slot - scoped

Note: you can use event handlers like click in de slot but this will change the node state (collapsed or opened). If you don't want this behavior just add stop as modifier in the event (@click.stop="clickHandler") or stopPropagation() (function clickHandler(e, node, isOpen) { e.stopPropagation()...})
