title: Grappelli - how to change text field size
body: <p>What is the best way to change text field size in Grappelli?</p>
  
  <p>Standard text field with vTextField class is 758px width.
  I looks strange when used for phone number field.</p>
  
  <p>I have figured out that one possibility is inject style attribute into form meta. </p>
  
  <p>class CompanyForm(ModelForm):</p>
  
  <pre><code>class Meta:
      model = Company
      widgets = {
          'phone': TextInput(attrs={'size': 13}),
          'tax_id': TextInput(attrs={'size': 6}),
          'zip': TextInput(attrs={'size': 6, 'style' : 'width: 80px'}),
      }
  </code></pre>
  
  <p>I am not sure this is the best solution and ....I do not like this (using style inline). Is there any other in the box solution?</p>
