title: Django form adding element before a field?
body: <p>Here is what my current form looks like</p>
  
  <pre><code>class sForm(forms.ModelForm):
  
      """Form to create new instance. """
      class Meta:
          model = sModel
          fields = ('title','twitter_username')
  
      def __init__(self, *args, **kwargs):
          super(sForm, self).__init__(*args, **kwargs)
  
          self.fields['title'].widget.attrs['placeholder'] = 'Title'
  
          self.fields['twitter_username'].widget.attrs['placeholder'] = '@twitter'
  </code></pre>
  
  <p>The form works absolutely fine. Now before the <code>twitter</code> element i want to add "@" symbol. Similar to <a href="https://codepen.io/anon/pen/dzxzBx" rel="nofollow noreferrer">this pen</a>. I am unsure how to do that ? thanks for helping me out</p>
