Looks good. Requested one change about the conditional rendering of children.

[b-yogesh]

Since the nodes are never undefined, because we send an empty array instead, a gap appears in the divider which is not an expected behaviour. The children code can be modified as below

Suggested change

	<Children nodes={nodes} onChange={onChange} />
	{nodes && nodes.length && <Children nodes={nodes} onChange={onChange} />}
