{#
   Default output for fields.

   This file is contains the 'sub_fields' Twig block tag.

   The 'sub_fields' Twig block is split into two parts:
    - The first section initializes the variables and settings, both from the
      ContentType definitions as well as passed in variables.
    - The last section is where the actual looping is done, and the relevant
      {{ block() }} function is called, for the 'ContentType fields',
      'repeater fields', 'block fields' and 'template fields' in turn.

   Read the relevant section in the documentation on usage of this
   functionality: https://docs.bolt.cm/templating

   For more information on using blocks, see the Twig documentation at:
    - https://twig.sensiolabs.org/doc/1.x/tags/block.html
    - https://twig.sensiolabs.org/doc/1.x/functions/block.html

                <code>block()</code> function, when using Preview. To view these fields, please
