I want to load URL( external URL '<http://google.com>') in Dashboard content,I tried with this code

```
 .state('app.urlloading', {
    url: '/url-loading',
    controller:function($window){

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

    },
    templateUrl: 'views/tmpl/url-loading.html'
  })

```

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.
