separate petgroups? Never heard of that. I have to use the workaround that pastamancer wrote.
Guessing the pet groups thing was a reference to this line in the patch notes:
- Players will now be able to pull out a pet window to see all the
pets in the raid.
The hope was that if Blizzard's interface could do it easily, then so could other unit frames. Probably not the case.
The SecureRaidHeader does not support pets. You'd have to pre-allocate frames for the maximum number of pets you want to display and then use the UnitWatch/SecureStateHeader combo to hide/show them. Blizzard gets around this because their code is secure and doesn't need/use the SecureTemplates.
