{# app/Resources/views/form/fields.html.twig #}

{# 
   here isn't need to create the expected `icon_choice_widget` like shown 
   the documentation, because this looks equal to `choice_widget` from 
   `ChoiceType`, only we need overwrite the block that renders the label. 
 #}

{%- block choice_widget_options -%}
    {% for group_label, choice in options %}
        {%- if choice is iterable -%}
            <optgroup label="{{ choice_translation_domain is same as(false) ? group_label : group_label|trans({}, choice_translation_domain) }}">
                {% set options = choice %}
                {{- block('choice_widget_options') -}}
            </optgroup>
        {%- else -%}

            {# this line has been overwritten, see {{- block('choice_option_label') -}} to end #}
            <option value="{{ choice.value }}"{% if choice.attr %} {% set attr = choice.attr %}{{ block('attributes') }}{% endif %}{% if choice is selectedchoice(value) %} selected="selected"{% endif %}>{{- block('choice_option_label') -}}</option>

        {%- endif -%}
    {% endfor %}
{%- endblock choice_widget_options -%}

{%- block choice_option_label -%}
    {# this block has been called from choice_widget_options block #}

    {%- if raw_label|default(false) -%}
        {# the label is rendered as raw when IconChoiceType is used #}
        {{ choice_translation_domain is same as(false) ? choice.label|raw : choice.label|trans({}, choice_translation_domain)|raw }}
    {%- else -%}
