我在编辑表单上为表单集合呈现树枝时遇到问题。表单加载没有问题，但集合字段的标签增加了一倍，并从选项修改为数字，jsfiddle将显示我的意思。
- html的jsfiddle输出
- 还有一张截图
Twig模板：
{% block body %}
<div class="row">
<div class="col-md-12">
<a href="#" class="add-choice btn btn-default" aria-label="Add Choice">
<span class="glyphicon glyphicon glyphicon-plus" aria-hidden="true"></span>
Adauga Camp
</a>
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="panel panel-default">
<div class="panel-heading">
<h1>Editeaza intrebarea</h1>
</div>
<div class="panel-body">
{{ form_start(edit_form, {'attr': {'class': 'form-horizontal'} } ) }}
<div class="row">
<div class="form-group">
{{ form_label(edit_form.question, null, {'label_attr': {'class': 'col-sm-2 control-label'} } ) }}
<div class="col-md-8">
{{ form_widget(edit_form.question, {'attr': {'class': 'form-control'} } ) }}

{{ form_widget(edit_form) }}
<div class="row">
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">

{{ form_end(edit_form) }}

{{ form_end(delete_form) }}
</div>
</div>
</div>
</div>
</div>
</div>
</div>
{% endblock %}
字段的Twig：
{% block _survey_question_answerId_entry_widget %}
<div class="row multiple-choice-container">
<div class="form-group">
{{ form_label(form.value, null, {'label_attr': {'class': 'col-sm-2 control-label'} } ) }}
<div class="col-md-8">
<div class="input-group">
<div class="input-group-addon">
<span class="glyphicon glyphicon-record" aria-hidden="true"></span>
</div>
{{ form_widget(form.value, {'attr': {'class': 'form-control'} } ) }}
{{ form_errors(form.value) }}
</div>
</div>
<div class="col-md-2">
<div class="btn-group">
<a href="#" class="add-choice btn btn-default" aria-label="Add Choice">
<span class="glyphicon glyphicon glyphicon-plus" aria-hidden="true"></span>
</a>
<a href="#" class="remove-choice btn btn-default" aria-label="Remove Choice">
<span class="glyphicon glyphicon glyphicon-minus" aria-hidden="true"></span>
</a>
</div>
</div>
</div>
</div>
{% endblock %}
->add('answerId', CollectionType::class, [
'entry_options' => [
'label' => false,
],
'entry_type' => AnswerType::class,
'allow_add' => true,
'allow_delete' => true,
'label' => false,
'by_reference' => false,
])
这应该完成
删除{{ form_label(form.value, null, {'label_attr': {'class': 'col-sm-2 control-label'} } ) }}
在表单类型中将标签设置为false
示例：
$builder->add('yourAttribute', null, array('label' => false));
