- Field collection
- -----------------
- Provides a field collection field, to which any number of fields can be attached.
- Each field collection item is internally represented as an entity, which is
- referenced via the field collection field in the host entity. While
- conceptually field collections are treated as part of the host entity, each
- field collection item may also be viewed and edited separately.
- Usage
- ------
- * Add a field collection field to any entity, e.g. to a node. For that use the
- the usual "Manage fields" interface provided by the "field ui" module of
- Drupal, e.g. "Admin -> Structure-> Content types -> Article -> Manage fields".
- * Then go to "Admin -> Structure-> Field collection" to define some fields for
- the created field collection.
- * By the default, the field collection is not shown during editing of the host
- entity. However, some links for adding, editing or deleting field collection
- items is shown when the host entity is viewed.
- * Widgets for embedding the form for creating field collections in the
- host-entity can be provided by any module. In future the field collection
- module might provide such widgets itself too.
- Using field collection with entity translation
- -----------------------------------------------
- * Field collection items must be selected as a translatable entity type at
- Admin -> Config -> Regional -> Entity Translation.
- * The common use case is to leave the field collection field untranslatable
- and set the necessary fields inside it to translatable. There is currently
- a known issue where a host can not be translated unless it has at least
- one other field that is translatable, even if some fields inside one of
- its field collections are translatable.
- * The alternate use case is to make the field collection field in the host
- translatable. If this is done it does not matter whether the inner fields
- are set to translatable or not, they will all be translatable as every
- language for the host will have a completely separate copy of the field
- collection item(s).
