CSS accordion menu - How to expand and hyperlink <div>

Question

I've taken a complex Accordion Menu design, and reduced the HTML and CSS to as basic and clean as possible.

1) The "AAA - Expanded" menu link is expanded with a specified "height: 75px". Which means I would have to calculate the total height of the combined sub-menu "li" list-items for each top level menu item. Is there a way to just specify which top level menu item I want expanded without having to determine the desired expanded height size?

2) The "CCC - No SubMenu" menu item links to an external page (not to expand the sub-menu) and so it only clickable on the TEXT itself. However, with the other sub-menu links, the entire "li" tag is clickable. I can't find the difference as to why this is not the case with "CCC". I'd like to make the whole DIV tag clickable. Any ideas?

<div id="acdnmenu">
    <ul class="top">

        <li><div class="topItem"><div class="arrowImage"></div>AAA - Expanded</div>
            <ul style="height: 75px;" c="1">
                <li><a href="http://www.Google.com">Google</a></li>

            </ul></li>

        <li><div class="topItem"><div class="arrowImage"></div>BBB - News</div>
            <ul>

                        </ul></li>
                    </ul></li>

        <li><div class="topItem"><a href="http://www.soflorealty.com">CCC - No SubMenu</a></div></li>
    </ul>
