How to bring a dropdown list behind the whole menu?

Hi, my name is James.

Trying to bring the dropdown list behind the whole menu so that when hover on the dropdown the list goes behind the menu not above.

I would assume by giving a negetive z index that would work but so far anything i’ve tried does not work. If there is no way around this, would custom code fix the problem?

Thanks y’all.
