AngularJS - animating items from one container into another container

Question

I have two divs, one starts empty, the other has some predefined items. On clicking items in one list, the other list gets items added to it.

What I would like to achieve is to animate items from one list to appear to physically move to the other. (I would like items to move from right to left). I don't know too much about CSS animations, or AngularJS animation. In jQuery, I could just call $().animate() on the div id to modify the properties.

How would I go about doing the same thing in AngularJS?

JS:

var app = angular.module('app', []);

app.controller('Ctrl', function ($scope) {

  $scope.selectedItems = [];
  $scope.items = ['a', 'b', 'c'];

});

HTML:

<div ng-controller="Ctrl">

<div class='container'> 
  <div class='inline selected-container' >
    <div ng-repeat='selected in selectedItems track by $index'> <!-- I would like items to appear here after items from other container have finished moving -->
      {{selected}}
    </div>
  </div>

  <div class="inline">
    <!-- I would like to push these items left on click -->
    <div class='inline box' ng-repeat="item in items" ng-click="selectedItems.push(item);"> 
      {{item}}
    </div>
  </div>
</div>

</div>

I read a decent explanation of ng-animate on this page : http://www.jvandemo.com/how-to-create-cool-animations-with-angularjs-1-2-and-animate-css/

Essentially, you need to define animations in your CSS, then attach ng-enter and ng-leave to your classes which you want to implement those animations.

/* Define your Animation , or just download animate.css which has all these defined*/ 
@-webkit-keyframes fadeOutLeft {
  0% {
    opacity: 1;
    -webkit-transform: translateX(0);
    transform: translateX(0);
  }

  100% {
    opacity: 0;
    -webkit-transform: translateX(-20px);
    transform: translateX(-20px);
  }
}

@keyframes fadeOutLeft {
  0% {
    opacity: 1;
    -webkit-transform: translateX(0);
    -ms-transform: translateX(0);
    transform: translateX(0);
  }
  100% {
    opacity: 0;
    -webkit-transform: translateX(-20px);
    -ms-transform: translateX(-20px);
    transform: translateX(-20px);
  }
}
.fadeOutLeft {
  -webkit-animation-name: fadeOutLeft;
  animation-name: fadeOutLeft;
}

You have to attach animations to your elements in the CSS:

/* Apply your animation, which will run on ng-repeat, ng-hide, ng-show, etc */
.item {
   /* this is the element you're animating  */
}
.item.ng-enter {  /* attach ng-enter */
    -webkit-animation: fadeInLeft 1s;
    -moz-animation: fadeInLeft 1s; 
    -ms-animation: fadeInLeft 1s;
    animation: fadeInLeft 1s;
}
.item.ng-leave { /* attach ng-leave */
    -webkit-animation: fadeOutLeft 1s;  /*  */
    -moz-animation: fadeOutLeft 1s;
    -ms-animation: fadeOutLeft 1s; 
    animation: fadeOutLeft 1s;
}
