Prevent page scrolling when an AngularJS dropdown is active

When using the angularjs dropdown, I encounter an issue where scrolling to the end of each side of the content triggers scrolling of the body, which can be quite bothersome. Is there a way to prevent the body document from scrolling when the dropdown is displayed?

For example, if you click on "Select item..", you can still scroll by following this link: http://jsfiddle.net/hAnGA/7/

<div ng-controller="MyCtrl">

    <drop-down list="dropdown" current="category" group="groupone"></drop-down>    

    <br/><br/>

    {{ category | json }}

</div>

Thank you!

To ensure the dropdown is open, it's important to include a check within your directive and then implement a scroll event listener as shown below:

if (scope.open) {                        
  window.addEventListener('scroll', function(e) {
    e.preventDefault();
    return false;
  })            
}
