"Sora Article" sub-menu support missing?

I see that the nav is controlled via user>config>site.yaml. Even if I roll my own css for subnav support + mobile, I don't suppose there is a way to input sub-links into a yaml file, is there? Of course at that point I might as well input my own html in the navigation.html.twig...

Probably best to submit an issue here: https://github.com/getgrav/grav-theme-soraarticle/issues

Yes, will do. Thanks.

Since there is no mention of this on the issue page, I thought I would share my findings with anyone stumbling on this as I did.

To fix the mobile menu just copy and replace the loop from navigation into the base template where the mobile drop-down is called.

Hope this helps someone.
