loading external URL on Dashboard Content
<p>I want to load URL( external URL '<a href="http://google.com" rel="nofollow">http://google.com</a>') in  Dashboard content,I  tried with this code</p>

<pre><code> .state('app.urlloading', {
    url: '/url-loading',
    controller:function($window){

      $window.location.href = 'https://google.com';

    },
    templateUrl: 'views/tmpl/url-loading.html'
  })
</code></pre>

<p>1) Is it possible to load a  external URL in Dashboard content ?, If I click a button  on  sidebar of the dashboard  only dashboard content should display the URL retaining sidebar and header, now whole dashboard is disappearing after clicking the button then redirecting  to the google page.</p>
