What differentiates sibling from child node?

[KarlM]

They seem to be moreorless the same as far as I can tell from the demo you've kindly afforded potential customers?

Sibling is at the same level.
Child has a parent.

Parent A (sibling of Parent B)

Child 1 of Parent A (sibling of Child 2)
Child 2 of Parent A (sibling of Child 1)​

Parent B (sibling of Parent A)

Child 1 of Parent B​

Yeah, that's what I thought... I just expected sibling to visually at the same level. So in essence, it's another parent forum.

It's only a parent if it has children.

A node can be both a sibling and parent at the same time.
