Tom, so far I am working on this (one page design with GP and sections) but I am not able to find out the correct navigation settings, so that the menu items are correctly highlighting the active section – can you help with may be any experience using “Scroll to ID”-Plugin, which is quite good, but does not seem to work out of the box?
this is a very old thread. But Sections are still the simplest way to create a single page layout. We have a Gutenberg Section Block in development, awaiting for Gutenberg to fix a bug, that will also do this. If you need any specific help, can i suggest raising a new topic 🙂
