#navMenu {

2.在這段程式碼
<div id='header-wrapper'>
<b:section class='header' id='header' maxwidgets='1' showaddelement='no'>
<b:widget id='Header1' locked='true' title='你的部落格名稱' type='Header'/>
</b:section>
</div>

下方加上自訂義的下拉式導航列
<!-- start nav -->
<div id='navMenu'>
<div id='navMenuleft'>

<ul id='nav'>
    <li><a expr:href='data:blog.homepageUrl'>Home</a></li>

    <li><a href='欲連結網址'>第1層</a>
        <ul><li><a href='欲連結網址'>第二層1</a></li>
            <li><a href='欲連結網址'>第二層2</a>
                <ul><li><a href='欲連結網址'>第3層1</a></li>
                    <li><a href='欲連結網址'>第3層2</a></li>
                </ul>
            </li>
        </ul>
    </li>

<li><a href='欲連結網址'>Tips and Trick</a></li>

</ul>

</div>
</div> <!-- end nav -->
