I would like to have at least one north of how to make a custom menu as in this image.
(In the image, the mouse is hovered on Sustainability.)
The vertical menu, with the submenu in the sequence, is fine. The problem comes in the sequence, which is getting the list one below the other.
Please, I need only one north of where I can watch some video lesson or access a document about it, or how to do it.
Thank you.
