[support] show submenu in block when parentmenu is clicked

[Morten Holmstrup]

Hi, I'm trying to achieve something that seems simple, but is really
killing me :(

This is Drupal 6.1

I have some primary links.
When I click one of these links I would like a submenu to appear in a
block elsewhere on the page - that's really all (for now). 

I just can't get it working - I've looked through every module and a lot
of functions in the d6 api, but no luck so far.

and deadline is closing in - yikes!

cheers
Morten
