Hi i am trying to figure out how to make a drop down menu on the business catalyst admin console

My menu content holder code is

    </li>

    <li>

    <a href="/clicker.html">Clicker</a>

    </li>

    <li>

    <a href="/contact.html">Admin App</a>

    </li>

    <li>

    <a href="/documentary.html">Documentary</a>

    </li>

    <li>

    <a href="/quiz.html">Quiz</a>

    </li>

    <li>

    <a href="/game">Game</a>

    </li>

    <li>

    <a href="/Previewer.html">Code Previewer</a>

    </li>

</ul>

unfortunately my dashboard looks like this
