I want a solution that allows us to display attributes grouped by attribute-sets on frontend. Each attribute-set-group should be displayed as headline and after headline, the attributes show up.
When I was working on Magento 1.9 I found a solution in the this link
But that doesn't work with Magento 2.1. I want something like this.
I found the two file responsible for doing that but I'm not familiar with Magento structure to modify them.
