title: Only show the arrowbutton of a spinner
body: <p>I would like to use a spinner but only show the arrow on the right side like Android does in it's settings menu. (like for example by Screen timeout)</p>
  
  <p>I can set the width to +/- 65px but then I've only got rounded corners on the rightside and not the left.</p>
  
  <p>Thnx for your help!</p>
