I tried lazyBehavior="unmount" (which is the default). Anyway, it doesn't getting unmounted when tab changes..

CodePudding user response：

I think you are additionally missing:

isLazy={true}

Docs for the lazyBehavior prop say:

The lazy behavior of tab panels' content when not active. Only works when isLazy={true}
