Thanks Alexandre.  That works well for when elements are removed.  Could you also extend the example so that the bounding box shrinks dynamically as items are dragged around.
For example, if I drag for node '10' downwards, currently the parent extent grows dynamically, but if I move '10' back to its original position, it does not shrink.

Hi Ben!

You will find a first shoot of this feature. Using the Mondrian DSL, you can have:

	outterNode := view node: 'hello' forIt: [ 
	view shape rectangle withText.
	view interaction on: ROMouseClick do: [ :event | 
		outterNode removeElement: event element. 
		ROHorizontalLineLayout on: outterNode elements.
		
		ROShrikingSize on: outterNode. 
		event element signalUpdate  ].
	 
	view nodes: (1 to: 20).
	].

It is also available from the Example/Mondrian/interactions/shrikingSize menu.

In Roassal 1.118

Cheers,
Alexandre

Just one more thing that has been playing on my mind.  It is really a nice feature that the parent element grows when the child is moved past its boundary, but would be more good if it also shrank when the child element is moved back towards center.
