title: Display optgroup label as initial option
body: <p>Is it possible to show the label of an optgroup in a select dropdown as the first option?</p>
  
  <p>Does this make sense? Or is there a better way to do it?</p>
  
  <p>I basically need a first label that shows like Select Price and that isn't directly selectable, but shows when you expand the select menu like an optgroup label does.</p>
