More Than One Menu Item?

Hello,

I’ve been trying to sort out how to have more than one sub-menu item on a menu bar.

For example:
https://techblog.kjodle.net/

This blog has a menu bar on top that contains 9 sub-menu items, 5 of which are dropdown sub-menu items. (I hope I’m using the correct terminology.)

Using the Weaver Theme Plus I’m able to create a menu that displays in the menu bar (called “Primary Navigation”. This is what I have:
https://pt127.org/

The menu is “Crew” and there are menu items subbed under it.

I’d like to add another menu, “Documents”, that would appear next to the “Crew” menu on the same menu bar. Just as “WordPress” appears next to “Home” in the https://techblog.kjodle.net/ example.

But, I’m lost. ??

Thanks for any help or suggestions,

Kathy K.
