title: Django form.MultipleChoiceField . Customize checkboxes in template
body: <p>I have this form:</p>
  
  <pre><code>class PasswordForm(forms.Form):
  
      CHOICES=[('uppercase','Uppercase'),
              ('lowercase','Lowercase'),
              ('numbers','Numbers'),]
  
      password_length = forms.ChoiceField(choices=[(x, x) for x in range(1, 32)],)
      options = forms.MultipleChoiceField(
                       widget=forms.CheckboxSelectMultiple, choices=CHOICES,)
  </code></pre>
  
  <p>How can I customize in template my checkbox fields?<br>
  I know how I can do it with other fields, like <code>forms.Charfield()</code> or my <code>password_length</code>, just  </p>
  
  <pre><code>&lt;form action="" method="post"&gt;
      {{form.some_field}}
  &lt;/form&gt;
  </code></pre>
  
  <p>but it doent works with my <code>MultipleChoiceField</code>, I tried many things like<br>
  <code>{{form.uppercase}}</code>, <code>{{form.options.choices.uppercase}}</code> and tried <code>{% for %}</code> loop.<br>
  it just return nothing, and I dont see it in html via browser inspector.</p>
