This is a test of nesting grouping. First, nested highlander grouping:
[expand title="This" rel="main-highlander"]
[expandsub1 title="This One" rel="this-highlander"]One[/expandsub1]
[expandsub1 title="This Two" rel="this-highlander"]Two[/expandsub1]
[expandsub1 title="This Three" rel="this-highlander"]Three[/expandsub1]
[/expand]
[expand title="That" rel="main-highlander"]
[expandsub1 title="That One" rel="that-highlander"]One[/expandsub1]
[expandsub1 title="That Two" rel="that-highlander"]Two[/expandsub1]
[expandsub1 title="that Three" rel="that-highlander"]Three[/expandsub1]
[/expand]This
This One
One
This Two
