Setting up a view and displaying it as a reference method for an entity reference field is pretty straight forward in D8. (a very good tutorial in case anyone needs)
In a few easy steps you can configure the few to your liking with search fields and inline fields. In my case it is a content view and the sample output I get in the views configuration page is:
Title / Field1 / Field2
which is perfectly how it should look like.
The problem is, in content form, I only get the Title listed. The search fields work very well but only the title is displayed in the entity reference field option list. I tried Select list (Chosen enabled or not), Autocomplete, Checkboxes/radio buttons. Also tried to rewrite results on various fields.
What am I missing here?
