[QUESTION] What is the best way to manage dynamic components?

Hi, can you please tell me what is the best way to manage dynamic templates. I want to describe you what's my case.

1. Have e-commerce store and use GrapesJS.
2. We have PAGES and in this pages want to add product collections or collection with brands (logo).
3. I want to create few components like product collection, brand collection, blog posts and ect.
4. I don't want user to write PHP code because can make REALLY big mess. I use SAMRTY as a template engine.

Let's check the following example:

1. Create a product collections - collection 1, collection 2 and collection 3.
2. Create new page and drag component "product collection".
3. In this component I choose from already added collections.
4. Between this components I add text, images, links ect.
5. Save the page and preview it.
6. On the place of components "products collections" I want to see all the products that I add from the CMS.
