i have the following problem in Drupal 8.

In custom content type there is a field, which is a multiple entity reference to the same content type. The field is set to use custom view mode, where only title and body fields are displayed. Kind of sub-pages structure. Also the content type has a boolean field, which determines whether the body field of sub pages (entity reference) should be displayed or not. So in my theme_preprocess_field() hook i can get the boolean value, but i don't know how to pass it to the entity references, so in my node--mypage--grid-item.html.twig i could check for that flag and determine should be content.body be rendered or not.

Thank for any hints.
