rendered_entity_list_formatter

Rendered Entity List Formatter provides a new more accessible formatter for entity reference fields.
This formatter wraps the rendered entities in a <ul><li> list if the field is a multiple reference, or in a <div> if it contains only a single item. This structure helps meet accessibility requirements for item listings.

Post-Installation

Install as you would normally install a contributed Drupal module.
After installation, this module adds a new field formatter for the entity reference field in the manage display of any entity type.

This formatter presents the same options as the rendered entity field formatter allowing you to choose different view modes. It simply wraps the output with the required tags to follow accessibility requirements
