title: Is there option group on Vuetify?
body: <p>I'd like to have a <code>option group</code> (like <a href="https://developer.mozilla.org/pt-BR/docs/Web/HTML/Element/optgroup" rel="noreferrer">this</a>) on a vuetify <code>select</code>. </p>
  
  <p>Is that possible? And if it is, how do I do it? </p>
