      &lt;ul class="tonho"&gt;&lt;li&gt;&lt;a href=""&gt;Sub 1.1&lt;/a&gt;
          &lt;/li&gt;
          &lt;li&gt;&lt;a href=""&gt;Sub 1.2&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;a href=""&gt;Sub 1.3&lt;/a&gt;
          &lt;/li&gt;
      &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;&lt;a href=""&gt;Menu 2&lt;/a&gt;
              &lt;ul class="tonho"&gt;&lt;li&gt;&lt;a href=""&gt;Sub 2.1&lt;/a&gt;
              &lt;ul class="tonho"&gt;&lt;li&gt;&lt;a href=""&gt;Sub Sub 2.1.1&lt;/a&gt;
                  &lt;/li&gt;
                  &lt;/ul&gt;                 
                  &lt;/li&gt;
                  &lt;li&gt;&lt;a href=""&gt;Sub 2.2&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  &lt;/li&gt;
  &lt;li&gt;&lt;a href=""&gt;Menu 3&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p></p>
  
  <p>Edit: I can't give level 1, 2 etc to the because this menu is being generated by PHP + SQL script.</p>
