Thanks a million for your response and your help. Set it up exactly as you advised.

Works perfectly except one thing. Please let me know what I did wrong.

On Mobile, when I click on the first tab, it shows what should be there… Group A. But, when I click on the 2nd tab, it stays showing group A, but opens group B above, so to see it, I have to scroll up. And if I click on group C, now both A and B are displayed and Group C is added to the top and so on. How do I have it display just the group that I click on?

Thanks in advance for answering.

Please advise on how to fix. I cant figure it out.
