I wanted to create a much more deep and complicated menu system for my Flying-Higher.com site because of how I want to lay out what might ought to be two websites (Creator Services & Creator Tools) in as elegant and integrated a way as possible.
This has all lead to a complete re-write of the site while learning the ways of Elementor Pro and Elemental Menu. The standard WordPress Gutenberg editor is great, but limited in layout options, especially since those options are really needed for creating Mega Menus.
At some point I want to make a video about this. This is the only way I can see to have tons of control of information architecture using WordPress.
