title: Laravel add multiple classes when using Form::open()
body: <p>Currently I have a form that looks like this:</p>
  
  <pre><code>{!! Form::open(['route' =&gt; 'lists.store', 'class' =&gt; 'form1']) !!}
  </code></pre>
  
  <p>I was wondering how can I add multiple classes something like the following</p>
  
  <pre><code>{!! Form::open(['route' =&gt; 'lists.store', 'class' =&gt; 'form', 'blah', 'blah2']) !!}
  </code></pre>
  
  <p>I am expecting the result to be:</p>
  
  <pre><code>&lt;form class="form blah blah2" ...
  </code></pre>
  
  <p>but instead i just get an error.</p>
