How many products can I add in a block?
You can add all products or just a section from the Product catalog to blocks containing cards (ST300, ST305N, ST310N, ST315N) from the "Store" category. You can add up to 5 000 items in total.
To make navigation smoother, it can be a good idea to group your products into different categories, display up to 100-200 items per page and organize them in blocks on separate pages.
