title: how to hide\show list items from button in angular js
body: <p>i have list of items and i want to create filter from button that shows\hides the element, instead of add\remove it from the DOM.</p>
  
  <pre><code>&lt;li ng-repeat="li in list" ng-show=""&gt;
  &lt;a ng-click=""&gt;category&lt;/a&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>i mean that instead of filtering list i want to hide\show list items by this filter.
  i found this fiddle  <a href="http://jsfiddle.net/cKa6K/" rel="nofollow">http://jsfiddle.net/cKa6K/</a></p>
  
  <p>but i want to do the same only with hide\show.</p>
