title: Using Chosen.js with Django
body: <p>Hello Im trying to implement chosen.js into my Django project and so far it works great. I only have one issue which I cannot solve. I have a model where "language" is a <code>ChardField</code>. I wanted to let the User choose more than one language so I tried to use chosen Multiple. Since a Charfield can only hold one Value so I used <a href="https://github.com/goinnn/django-multiselectfield" rel="nofollow noreferrer">Django Multiselect</a>. Now the Chosen.js is not working anymore and I have no idea what to do. 
  Models: </p>
  
  <pre><code>from multiselectfield import MultiSelectField
  
  class UserProfile(models.Model):
      language = MultiSelectField(verbose_name=_(u"Content Language"), 
       max_length=40, choices=settings.LANGUAGES,default='en')`
  </code></pre>
  
  <p>Forms: </p>
  
  <pre><code>class UserProfileForm(forms.ModelForm):
  class Meta:
      model = UserProfile
      fields=[
        'language',
           .....
        ]
  </code></pre>
  
  <p>Template: </p>
  
  <pre><code>{% load widget_tweaks %}
  {% csrf_token %}
  &lt;span&gt;Content language {{ form.language|add_class:"chosen-select" }}&lt;/span&gt;
  </code></pre>
  
  <p>So the question is how do I get the normal chosen.js input field to a multiple chosen field (with Django)? I know there is the possibility to add a multiple field to the forms but this messes up my hole code. </p>
