      <script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script>

      <script type="text/javascript" src="http://everything-about-blogging.googlegroups.com/web/hoverIntent.js?gda=OCoH4UAAAADAUWBlY8jxn6h_X6rBHvj4fINo3FqnP184lbsvRkkyX55SCaRh6rXo2PdRGn5gs_5txVPdW1gYotyj7-X7wDON"></script>

  <ul class="sf-menu">
    <li class="current">
        <a href="#a">Home</a>
    </li>
  </ul>
Result:

First step in creating jQuery menu


Now we will add menu item "Menu 2" right to Home item, it is new <li> in HTML code


<ul class="sf-menu">
    <li class="current">
        <a href="#a">Home</a>
    </li>
    <li class="current">
       <a href="#a">Menu 2</a>
    </li>  
 </ul>
Result:

Step two in building jQuery menu


To add two submenus to "Menu2" item we will open <ul> tag and put two <li> tags, one for each submenu


<ul class="sf-menu">
    <li class="current">
        <a href="#a">Home</a>
    </li>
    <li class="current">
       <a href="#a">Menu 2</a>
       <ul>
        <li><a href="#a">SubMenu1</a></li>
        <li><a href="#a">SubMenu2</a></li>
       </ul>
    </li>  
 </ul>

Result:

Add two submenus to menu item in jQuery drop down multi level menu


Last, we will add one 3rd level submenu "Blogger jQuery menu" to Submenu1 which link to this page. To do that one more <ul>, <li> tag are needed



<ul class="sf-menu">
    <li class="current">
        <a href="#a">Home</a>
    </li>
    <li class="current">
       <a href="#a">Menu 2</a>
       <ul>
        <li><a href="#a">SubMenu1</a>
         <ul>
            <li>
                 <a href="http://interestingwebs.blogspot.com/2009/11/jquery-drop-down-menu-for-blogger.html">jQuery menu</a>
            </li>
         </ul>
        </li>
        <li><a href="#a">SubMenu2</a></li>
       </ul>
    </li>  
 </ul>
Result:

Add third level submenu with link for jQuery multi level menu
