My content type have an "entity reference field" related to another content type.
The only option I have is to display a link to the entity.
How can I display other fields from this entity?
You can choose
rendered entity instead of
After that click the options button (cog wheel) and choose the
view mode of the rendered entity.
You can go the referenced content type's
manage display and modify the chosen
view mode to display the fields that you want
you can enable more display modes from
manage display > Default > custom display settings
and can also create your own
view mode by pressing
manage view modes on the bottom of the same screen
