title: yii2 active field template
body: <p>It seems template for checkbox in sample yii2 project doesn't not apply correctly</p>
  
  <pre><code>&lt;?= $form-&gt;field($model, 'rememberMe', [
      'template' =&gt; "&lt;div class=\"col-lg-offset-1 col-lg-3\"&gt;{input}&lt;/div&gt;\n&lt;div class=\"col-lg-8\"&gt;{error}&lt;/div&gt;",
  ])-&gt;checkbox() ?&gt;
  </code></pre>
  
  <p>what's wrong here?</p>
