I have a content type in a drupal 8 site with the layout as shown in the image, I have used css grid for the layout and every section( f1, f2, f3 ....) is a field which needs to have paragraph bundles in them (pb1, pb2, .......).
This is just one type of content type, i have another in which the amount of fields go up to 40+, not to forget the paragraph bundles in them which are a group of 3-4 paragraphs each.
I am concerned about the performance of the site now and later in time when the site grows, its a magazine site and content needs to be written everyday.
Any help appreciated, thanks :)
I've worked on sites with hundreds of node fields and generally found that nesting them within collapsible fieldsets and having them collapsed by default, stopped the long wait for the field javascript handlers to all load and kick-in on the initial page load.
But that only works if you have collections of fields that you'll rarely have to edit.
