I didn't get any response after attached my question to an old topic -Menu Advice. Besides, the old reference web sites are no longer available so that there is no way of knowing for sure if we have the same issue. Thus, I am posting under a new topic. Any advice is greatly appreciated.
In additional to the existing Blog theme menu items such as Home, Page1 and Page2(see green-bug-10 blog theme below by click on Test Run). I want to make a new menu item Page3, which has 3-level popup menu(i.e. Vertical Plain Text Menu -http://milonic.com/menusample2.php
). I have made Milonic 3-level popup menu work, but the top menu looks like a patch, that sits on top of the existing menu bar of the blog theme.  
How do I integrate Page3 of a 3-level popup menu with the existing green-bug-10 theme menu bar seamlessly?
The green-bug-10 defines its own style <ul> and <li> in Style.css. All the existing menu items are within
the <div><ul><li> block as follows:
<div id="menu">
      <ul>
         <li><a href="index.html">Home</a></li>
         <li><a href="index.html">Page1</a></li>
        <li><a href="index.html">Page2</a></li>
        <li><a href="index.html">Page3</a></li>
      </ul>   
   </div>
