I've tried a number of menus and various collapse/start_level options for my right-hand navigation and it seems that no matter what I can only display either my top level pages or every page on the site.
I figured it would be a simple case of using {menu template='simple_navigation.tpl' collapse='2' start_level='1'} but that showed all levels, not just the two I expected.
I also tried menu_icon_expand - when expanded, this is exactly what I need -- only without the 'expand' links (unless those can somehow be indented under each parent section link).
I am currently using this:
{cms_module module='menumanager' collapse='2' start_level='2'}
which is giving me much more than I want, but at least it's indented (screenshot here):

I essentially want to see 'Animal Bio' and its children (Cardian Electrophysiology, Clinical Hematology, etc.) listed, but not theirs - I want all the sub-pages for Cardiac Electrophysiology, for example, to not appear here.
Any ideas? I've done a lot of tinkering with the 'collapse' numbers, but it seems to be all or nothing for some reason.
Thanks!
