Hm. In that case, you’re probably better off implementing my solution, but as separate repeaters for each Flavour. You’ll need to put each repeater into its own dynamic panel, and then use the “push/pull widgets” function to have them stack correctly (or possibly another method of keeping them correctly stacked). Not that difficult really.
Incidentally, the fact that the “feature” isn’t part of Axure out of the box is, I think, a good thing. It would be unwise (and anyway impossible) for Axure to descend into being a massive library of UI patterns that you had to choose from. That’s for other tools to fail at.
Instead, Axure inhabits the intersection of speed, fidelity and creativity. It allows you to demonstrate almost any UI using fundamental concepts, while insulating you from writing code. And most importantly as you have discovered, it makes few assumptions about what you want because of that.
