How to get 2 drop down menus from sidebar.php

I am trying to get my bar across the top (it is a side bar) to have two different drop down menus.

One will say “mcp workshops” and the other “about”… I got that part working – but they both show the same categories underneath.

I have the pages set up – but I am not sure what sidebar code to get the new “workshops” to display its own pages instead of the ones for “about”.

Here is the code used in the sidebar,php – I assume I need to tell it to be a different # child – but what number – HELP PLEASE!!!

<?php wp_list_pages(‘title_li=’.__(‘mcp workshops’).’&child_of=80&depth=0′); ?>

<?php wp_list_pages(‘title_li=’.__(‘about’).’&child_of=80&depth=0′); ?>
