title: Find all li elements that have ul in them
body: <p>I have a list below, I want to add content after <code>li</code> elements what have <code>ul</code> elements in them. How can I do that with CSS or jQuery?</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li&gt; item 1 &lt;/li&gt;
      &lt;li&gt; item 2 
          &lt;ul&gt;
              &lt;li&gt; item 2.1 &lt;/li&gt;
              &lt;li&gt; item 2.2 &lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
      &lt;li&gt; item 3 &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
