title: How to show/hide an element based on its height using Angular?
body: <p>I want to show a "Read More" link if my paragraph height reaches 200px. What is an elegant way of doing it using Angular?</p>
  
  <p>My elements -</p>
  
  <pre><code>&lt;section class="mynotes" ng-if="MyController.mynotes"&gt;
  &lt;p ng-bind="MyController.mynotes" ng-class="{'showMore': more, 'showLess': !more}"&gt;&lt;/p&gt;
  &lt;section ng-click="MyOtherController.togglearrow($event)"&gt;
        &lt;i class="down-arrow"&gt;&lt;/i&gt;
        &lt;span ng-click="more = !more"&gt;{{more ? 'Less' : 'More'}}&lt;/span&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p></p>
  
  <p>I want to hide the arrow and the Less/More text based on the p height. Any ideas?</p>
