Question

wp shortcode data-filter-class ='[“london”，“art”]的动态如何？

<ol id="filters">
  <li data-filter="amsterdam">Amsterdam</li>

</ol>
<br/>

<div id="main" role="main">

  <ul id="tiles">

    <li data-filter-class='["london", "art"]'>
      <img src="../sample-images/image_1.jpg" height="283" width="200">
      <p>London Art</p>
    </li>
    <!-- End of grid blocks -->
  </ul>

</div>
