body: <p>I would appreciate if you help me, the problem is that I have a menu and it has a submenu, and this submenu has a class by default - sub-menu, how can I change this class to submenu and how can I add to my first li - tag - </p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;ul class="cf"&gt;
      &lt;li class="sub-menu"&gt;&lt;a href="about.html"&gt;managers&lt;i class="fa fa-angle-down fa-1g" aria-hidden="true"&gt;&lt;/i&gt;&lt;/a&gt;
          &lt;ul class="submenu"&gt;
              &lt;li&gt;&lt;a href="managers.html"&gt;page one&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="shareholder.html"&gt;page two/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
