<?php 
	$form = ActiveForm::begin([
		'action' => ['test/getpost'],
		'method'=>'post',
		'options'=>['class'=>'form form-horizontal'],
		'id'=>'form-dict-add',
		'fieldConfig'=>[
			'template'=> "{label}\n<div class=\"formControls col-xs-8 col-sm-9\">{input}</div>\n{error}",
			'labelOptions'=>['class'=>'form-label col-xs-4 col-sm-2'],
			'options'=>['class'=>'row cl'],
		]
	]); ?>

这么写options去改变外层生成div的class
