title: Generate dynamic css classes in laravel-blade
body: <p>I'm in a classical scenario where i want based on wheter an error has occurred or not to change the css classes. As shown below, where has-error should change accordingly.</p>
  
  <pre><code>&lt;div class="form-group has-error"&gt;
  </code></pre>
  
  <p>The project is in Laravel, where we mainly want to do everything in <code>Blade</code> as of now, we came up with the following solution which works, but does not look pretty or intuitive at all, so the question is, is there a more optimal way of doing this?</p>
  
  <pre><code>&lt;div class="form-group
  @if($errors-&gt;has('email'))
          has-error
  @endif
  "&gt;
  </code></pre>
