I've been messing around a bit with font settings and noticed that the bottom levels of dropdown menus fetch the font from the body, while the parent elements (expectedly) fetch the font from "Hornav Menu Font".
I want to use different fonts in menu and article/body and I don't think it's in the (template) creator's intention that the submenus behave differently than their parents.
I'm attaching an image which I configured in your demo.
Hornav Menu Font: Raleway
Body Font: Coming Soon
I don't know, if this bug exists in multiple templates.
And parallel:
It takes a lot of effort to look up all the pre-installed fonts on Google Fonts. If I haven't overlooked such things, a demo in your FAQ / tutorial wouldn't be bad, where you could include a Lorem Ipsum paragraph per font, so that one can see how it looks like.
