title: How to handle big list of items in drop-down angular-ui?
body: <p>I use <a href="http://angular-ui.github.io/bootstrap/#/dropdown" rel="noreferrer">angular-ui drop down</a> </p>
  
  <p>It works fine but I have no clue how to handle multiple item in drop down.</p>
  
  <p>Consider following example in <a href="http://plnkr.co/edit/tQCZ132Avu781p06Gn8R?p=preview" rel="noreferrer">Plunker</a></p>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;div class="btn-group" dropdown is-open="status.isopen"&gt;
    &lt;button type="button" class="btn btn-primary dropdown-toggle" ng-disabled="disabled"&gt;
      Button dropdown &lt;span class="caret"&gt;&lt;/span&gt;
    &lt;/button&gt;
    &lt;ul class="dropdown-menu" role="menu"&gt;
      &lt;li ng-repeat="item in items"&gt;&lt;a href="#"&gt;{{item}}&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want define scroll and set dropdown shorter.</p>
  
  <p>Any ideas?</p>
