title: jquery select first child with class of a parent with class
body: <p>How can i select only the first child of a particular class of a parent with a particular class for the purposes of <code>clone()</code>?</p>
  
  <pre><code>&lt;div class="sector_order"&gt;
  
      &lt;div class="line_item_wrapper"&gt;
      SELECT THIS DIV
      &lt;/div&gt;
  
      &lt;div class="line_item_wrapper"&gt;
      NOT THIS DIV
      &lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>I am trying like this:</p>
  
  <pre><code>var form1 = $(this)
      .parents('.sector_order')
      .children('.line_item_wrapper')
      .children().clone(true)
  </code></pre>
  
  <p>and get both inner divs with the class <code>line_item_wrapper</code>, but I get an empty object when I try with this addition:</p>
  
  <pre><code>children('.line_item_wrapper :first')
  </code></pre>
  
  <p>Thanks!</p>
