Rules about cheerleaders' actions during play

[Jeffrey Moon]

I am not an official, just an observer/player parent, but I can't seem to get an answer to this q. In a game following the High School federation rules, may cheerleaders stand along the sidelines right beside the inbounds line and actually do cheers, kicks, dances, etc., during the time the ball is actually live or during foul shots? I had always been taught they could not--- could only do that during timeouts--- but after a recent game where a team did this continuously to distract opposition I was told by the ref there is no such rule, and that the only standard he has to apply is whether he subjectively thinks that its affecting play. I have a hard time believing this, since it really means there is no rule at all. Can anyone tell me what the rule is, and give the the exact Rule number? Thanks a lot!
