在我的表单类型中我有这个:
$builder
->add('options', 'choice', [
'choices' => $choices,
'multiple' => true,
'expanded' => true,
'label' => false
])
;
选择是一个数组:
$choices = [
'val1' => 'val1',
'val2' => 'val2',
'val3' => 'val3'
];
太棒了!现在我想用这样的数组对我的选择进行分类:
$choices = [
'label1' => [
'val1' => 'val1',
'val2' => 'val2',
],
'label2' => [
'val3' => 'val3',
'val4' => 'val4',
],
'label3' => [
'val5' => 'val5',
'val6' => 'val6',
],
];
所以我想要下面的结果
实现这一目标的最佳方法是什么?

您可以覆盖此选择字段的窗口小部件并手动呈现标签
像这样(以你的形式填写):
{% form_theme putYourFormNameHere _self %}
{% block _putYourFormNameHere_options_widget %}
<div {{ block('widget_container_attributes') }}>
{% for group_label, group in choices %}
{%- if group is iterable -%}
<div>
<label><b>{{ group_label|trans({}, translation_domain) }}</b></label>
{% for key, choice in group %}
<div>
{{- form_widget(form[key]) -}}
{{- form_label(form[key]) -}}
<div>
{% endfor %}
</div>
{%- endif -%}
{% endfor %}
{% endblock %}
