  <p>In local setup, I get the select2 work, but I cannot set the width as described in the <a href="http://angular-ui.github.com/#directives-select2" rel="noreferrer">docs</a>. It is too narrow to be used.</p>

  <p>Thank you.</p>
  
  <p>EDIT:
  Never mind that plnkr, I found a working fiddle here
  <a href="http://jsfiddle.net/pEFy6/" rel="noreferrer">http://jsfiddle.net/pEFy6/</a></p>
  
  <p>It looks like it is the behavior of select2 to collapse to the width of first element. I could set the width through bootstrap <code>class="input-medium"</code> .Still not sure why angular-ui doesn't take config parameters.</p>
