Hi @J805 ! Thank you for the very elaborative example. I have a question regarding the order of the blog post body elements. If the blog post is a user generated content and that the user can arrange the blog post elements by themselves, for example text bloc 1 - image 1 - text bloc 2 - video 1… then how do I set up the UI/database in a way that can remember the order of those blog post body elements and eventually display it in order on the page?
You would do it the same way. The way I built the example is how you would build it for anyone. It doesn’t matter who builds it. 
The list of ‘blog body’s’ on the blog post would even allow you to easily use a drag and drop plugin to move the order of things around without having any type of order number being saved.
Does that make sense?
