title: Groups of buttons in angular-material
body: <p>Can I create the same functionality
  <a href="http://angular-ui.github.io/bootstrap/" rel="noreferrer">http://angular-ui.github.io/bootstrap/</a> (chapter: Buttons (ui.bootstrap.buttons)</p>
  
  <p>using angular-material?</p>
  
  <p>Angular-material has radio-button directive but I can’t use it because I don’t want “the dot” on the left side of the label.</p>
  
  <p>Angular-material has also select directive but it is not the same functionality. </p>
  
  <p>Do I have another options? </p>
