Render first element of a multivalued field On my site I've an image field, multi value.
I would like, on a custom view mode, to display only the first image. On the field formatter I don't have this option.

How should I do this? Directly from twig or I've to use a preprocess function? 

[EDIT] I would to do this without using a custom node template :)
Then it's

{{ content.field_name[0] }}



  Note: If you need to print the label use {{ content.field_name['#title'] }} as {{ content.field_name[0] }} does
  not print the label.
