Nested Tabs 2 open at a time.

[Chriller855]

In your demo i find that you have a problem in nested tabs if you click around in sub tab 2 and 3. then back to main tab.

I think it can be fixed with a little class container(all containers) display None then selected container display true.

I will be Looking forward to a fix.
