Hi Lyle,
I didn’t know you were part of GeneratePress, have interacted with you on Facebook a few times in the Elementor page.
I checked out your demo site and you were def getting there but with the header from the theme rather than Elementor.
I am not one for hand coding I am afraid which is why I am trying to have the menu overlay the body content.
I am using Elementor rather than Beaver Builder so shortcodes not an option as far as I am aware.
I am going to install Yellow Pencil and see if I can make progress with it.
Thanks for your time Lyle
