JS FULLPAGE Editor can add section (fullscreen div with txt and bg color) no cms

Hello, I am writing to you because I need to give my clients the possibility to add sections to pages created with jsfullpage and webflow. the idea is that the customer can add fullscreen sections to the page by modifying text, background color / background image.
All without using CMS. In a dynamic way, @ben has already helped me to create a structure but I would not want the limit of collections to create problems and it seems superfluous to use CMS sections for pages that will not be updated often.
This is the exemple of navigation i made with cms jsfullpage section
and i need to alternate this structure for project and a not dynamic structure for simple page if is possble.
many thanx
