Wordpress Theme -> Custom Nav Menu

Question

I'm pretty new at creating Wordpress themes, and I need some help with the navigation menu. The format for the navigation bar needs to be something like this:

<ul id="nav">
    <li class="top"><a href="#home" class="top_link"><span>Home</span></a></li>
    <li class="top"><a href="#page1" class="top_link"><span>My Page</span></a>
        <ul class="sub">
            <li><a href="#page1_1" >My Page _ 1</a></li>
            <li><a href="#page1_2" >My Page _ 2</a></li>
            <li><a href="#page1_3" >My Page _ 3</a></li>
            <li><a href="#page1_4" >My Page _ 4</a>
                <ul>
                    <li><a href="#page1_4_1">My Page _ 4 _ 1</a></li>
                    <li><a href="#page1_4_2">My Page _ 4 _ 2</a></li>
                    <li><a href="#page1_4_3">My Page _ 4 _ 3</a></li>
                </ul>
            </li>
        </ul>
    </li>
    <li class="top"><a href="#page2" class="top_link"><span>2nd Page</span></a>
        <ul class="sub">
            <li><a href="#page2_1">2nd Page _ 1</a></li>
            <li><a href="#page2_2">2nd Page _ 2</a></li>
            <li><a href="#page2_3">2nd Page _ 3</a></li>
        </ul>
    </li>
    <li class="top"><a href="#apage" class="top_link"><span>Another Page</span></a></li>
    <li class="top"><a href="#xpage" class="top_link"><span>xPage</span></a></li>
</ul>

And I'm sure you can tell how everything the pages should go.

You can try NAVT plugin for doing this. Its pretty configurable.
