I read this post about setting up a product catalog in SharePoint server 2013 https://blogs.technet.microsoft.com/tothesharepoint/2013/02/13/how-to-set-up-a-product-centric-website-in-sharepoint-server-2013, and I was looking for something similar to that but in SharePoint online, I did not found a complete tutorial online about Catalog feature in SharePoint online.
What do you suggest about the best way to make a product catalog in SharePoint Online?
