How do I change the hamburger menu to a more traditional menu beneath the site logo?
As much as we would love to help you on your request, but this feature is not in core. Also this is not a quick fix and therefore needs additional customization. In fact, it is the theme feature of displaying the menu feature in a extraordinary way as shown in its demo here. This feature could be available in future updates. Alternatively, you can consider Hiring a Customizer if you want.
I would like to have a tagline display below the site logo. How do I add the tagline?
Well, to add the tagline below the logo browser Appearance -> Customize -> Site Identity there you would see the “Tagline” field to input your text.
Too bad about the menu. I find the extraordinary method of displaying the menu too far out of the ordinary. I am surprised others have not felt the same way. For someone who has not encountered that method of accessing a sites menu it would cause me to immediately leave a site. It requires too many additional clicks to do something on a site.
I have tried that but a tagline will only display when there is no site logo.
@coachbb94, you feedback regarding the menu on current context is very much appreciating to us. Your thought is valuable and probably our users would get the optional setting to switch between these menu type in near future updates as already been enlisted.
At the moment, we apologize for any inconvenience you are having with it.
Next, regarding the tagline display with site logo is quite working fine as again tested and verified in current version. You can refer to the screenshot below.
That is theme is working fine. Let us know if you have any confusion on it.
