title: Displaying multiple Rows and Columns in django-crispy-forms
body: <p>I'm using <strong>django-crispy-forms</strong> with Twitter Bootstrap , and I'm having some issues with customizing my forms into multiple rows and columns. One example problem is that nothing happens when I try to split the form into two columns:</p>
  
  <pre><code>class SomeForm(ModelForm):
  
      helper = FormHelper()
      helper.layout = Layout(
          Column('field1', 'field3'),
          Column('field2', 'field4'),
          )
      )
  
      class Meta:
          model = Model
  </code></pre>
  
  <p>Looking at the html output, I see that there is the <code>&lt;div class="formColumn"&gt;</code>, but the form is displayed in one single column. Maybe is this an css issue? I am using Bootstrap 2.1.</p>
