BuddyPress.org

Hi,

I am developing a child theme for the Buddypress default theme. I am wanting to make significant changes to the html for nav menu items. It appears that the function wp_nav_menu generates the nav div html. From having read the info on creating child themes it would seem that the best approach is to create a functions.php file in my child theme directory and then add a new function there, say wp_nav_menu2, and then include this in my header.php. Having looked at the default functions.php file it is not clear to me what I need to copy over to my functions.php from the default version, and where I would add the html for my nav items. I would like the html for each nav item to be in the form:

<li>
<div class="box">
<div class="top"></div><div class="clear">
<div class="bottom" id="current">
<a href="index.html">
<div class="left"></div>
<div class="center">home</div>
<div class="right"></div>
</a>
</div>
</div>
</li>

Complicated markup I know, but it enables me to construct nav items from various background images.

Could someone advise me as to how to implement this?

Thanks,

Nick
