def render_fields(dictionary,
                  *fields,
                  **opts):
    '''
    This function works similarly to
    :mod:`render_field <salt.modules.napalm_formula.render_field>` but for a
    list of fields from the same dictionary, rendering, indenting and
    distributing them on separate lines.

    dictionary
        The dictionary to traverse.

    fields
        A list of field names or paths in the dictionary.

    indent: ``0``
        The indentation to use, prepended to the rendered field.

    separator: ``\\n``
        The separator to use between fields.

    CLI Example:

    .. code-block:: bash

        salt '*' napalm_formula.render_fields "{'mtu': 68, 'description': 'Interface description'}" mtu description

    Jinja usage example:

    .. code-block:: jinja

        {%- set config={'mtu': 68, 'description': 'Interface description'} %}
        {{ salt.napalm_formula.render_fields(config, 'mtu', 'description', quotes=True) }}

    The Jinja example above would generate the following configuration:

    .. code-block:: text

        mtu "68"
        description "Interface description"

    results = []
    for field in fields:
        res = render_field(dictionary, field, **opts)
        if res:
            results.append(res)
    if 'indent' not in opts:
        opts['indent'] = 0
    if 'separator' not in opts:
        opts['separator'] = '\n{ind}'.format(ind=' '*opts['indent'])
    return opts['separator'].join(results)
