  178.       <h1>Adding items</h1>
    179. 

  179.     
    180. 

  180. 

  181.     <p>If your application dynamically adds new content, Isotope provides several methods to add items.</p>
    182. 

  182. 

  183. <p><a href='../demos/adding-items.html'><strong>See Demo: Adding items</strong></a>.</p>
    184. 

  184. 

  185. <h2 id='additems_method'>addItems method</h2>
    186. 

  186. 

  187. <p>The <a href='methods.html#additems'><code>addItems</code> method</a> adds new content to an Isotope container. This applies the proper styles to the items so they can be positioned and any sorting data is retrieved. But that&#8217;s it. The new content will <em>not</em> be filtered, sorted, or positioned properly, nor will it be appended to the container element.</p>
    188. 

  188. <div class='highlight'><pre><code class='javascript'><span class='kd'>var</span> <span class='nx'>$newItems</span> <span class='o'>=</span> <span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&#39;</span><span class='p'>);</span>
    189. 

  189. <span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;#container&#39;</span><span class='p'>).</span><span class='nx'>append</span><span class='p'>(</span> <span class='nx'>$newItems</span> <span class='p'>).</span><span class='nx'>isotope</span><span class='p'>(</span> <span class='s1'>&#39;addItems&#39;</span><span class='p'>,</span> <span class='nx'>$newItems</span> <span class='p'>);</span>
    190. 

  190. </code></pre>
    191. 

  191. </div>
    192. 

  192. <h2 id='insert_method'>insert method</h2>
    193. 

  193. 

  194. <p>More likely, you want to use the <a href='methods.html#insert'><code>insert</code> method</a>, which does everything that <code>addItems</code> misses. <code>insert</code> will append the content to the container, filter the new content, sort all the content, then trigger a <code>reLayout</code> so all item elements are properly laid out.</p>
    195. 

  195. <div class='highlight'><pre><code class='javascript'><span class='kd'>var</span> <span class='nx'>$newItems</span> <span class='o'>=</span> <span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&#39;</span><span class='p'>);</span>
    196. 

  196. <span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;#container&#39;</span><span class='p'>).</span><span class='nx'>isotope</span><span class='p'>(</span> <span class='s1'>&#39;insert&#39;</span><span class='p'>,</span> <span class='nx'>$newItems</span> <span class='p'>);</span>
    197. 

  197. </code></pre>
    198. 

  198. </div>
    199. 

  199. <h2 id='appended_method'>appended method</h2>
    200. 

  200. 

  201. <p>The <a href='methods.html#appended'><code>appended</code> method</a> is a convenience method triggers <code>addItems</code> on new content, then lays out <em>only the new content</em> at the end of the layout. This method is useful if you know you only want to add new content to the end, and <strong>not</strong> use filtering or sorting. <code>appended</code> is the best method to use with Infinite Scroll.</p>
    202. 

  202. 

  203. <p><a href='../demos/infinite-scroll.html'><strong>See Demo: Infinite Scroll</strong></a>.</p>
    204. 

  204. 

  205. <p>See also <a href='help.html#infinite_scroll_with_filtering_or_sorting'>Infinite Scroll with filtering or sorting</a></p>
    206. 

  206. 

  207. <h2 id='prepending'>Prepending</h2>
    208. 

  208. 

  209. <p>Because of Isotope&#8217;s sorting functionality, prepending isn&#8217;t as straight forward as might expect. However, it can be replicated fairly easy. After prepending new content to the container, you can re-collect all the item elements and update their sorting order with the <a href='methods.html#reloaditems'><code>reloadItems</code> method</a>. Then trigger a re-layout, with the original DOM order.</p>
    210. 

  210. <div class='highlight'><pre><code class='javascript'><span class='kd'>var</span> <span class='nx'>$newItems</span> <span class='o'>=</span> <span class='nx'>$</span><span class='p'>(</span><span class='s1'>&#39;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&lt;div class=&quot;item&quot; /&gt;&#39;</span><span class='p'>);</span>
