  179.     <p>Isotope can hide and show item elements via the <a href='options.html#filter'><code>filter</code> option</a>. <code>filter</code> accepts a jQuery selector. Items that match that selector will be shown. Items that do not match will be hidden.</p>

    184.

  198. <h2 id='jquery_script'>jQuery script</h2>
    199. 

  199. 

  200. <p>To show only <code>.metal</code> items, the jQuery script would be:</p>
    201. 

  201. <div class='highlight'><pre><code class='javascript'><span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;#container&#39;</span><span class='p'>).</span><span class='nx'>isotope</span><span class='p'>({</span> <span class='nx'>filter</span><span class='o'>:</span> <span class='s1'>&#39;.metal&#39;</span> <span class='p'>});</span>
    202. 

  202. </code></pre>
    203. 

  203. </div>
    204. 

  204. <p>The <code>filter</code> option uses a <a href='http://api.jquery.com/category/selectors/'>jQuery selector</a> to show item elements that match a selector, and hide all others that do not. For example:</p>
    205. 

  205. 

  206. <ul>
    207. 

  207. <li><code>.alkali, .alkaline-earth</code> will show <code>.alkali</code> AND <code> .alkaline-earth</code> item elements.</li>
    208. 

  208. 

  209. <li><code>.metal.transition</code> will show item elements that have BOTH <code>.metal</code> and <code>.transition</code> classes.</li>
    210. 

  210. 

  211. <li><code>.metal:not(.transition)</code> will show <code>.metal</code> item elements that are NOT <code>.transition</code>.</li>
    212. 

  212. </ul>
    213.
