title: Class 'yii\bootstrap\ActiveForm' not found
body: <p>I am using a <strong>Yii2</strong> advanced app. The back end is fine, but I'm having a problem when I try to create a page (e.g., abc.php) in the front end/views folder, and then try to use a bootstrap ActiveForm class. For example:</p>
  
  <pre class="lang-php prettyprint-override"><code>&lt;?php
  
   use yii\helpers\Html;
   use bootstrap\ActiveForm;
  
  ?&gt;
  
  &lt;div class="client-vehicle-info-form"&gt;
  
  &lt;?php $form = ActiveForm::begin(['layout' =&gt; 'horizontal']); ?&gt;
  
  &lt;?php ActiveForm::end(); ?&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p></p>
  
  <p>Here is the error I am getting:</p>
  
  <pre class="lang-none prettyprint-override"><code>Fatal error: Class 'bootstrap\ActiveForm' not found in C:\xampp\htdocs\MyApp\frontend\views\abc.php on line 10
  </code></pre>
