menu issues

hi guys,

I am pretty new to modx and I am trying to set up a modx website.
I a struggling with a menu. Hope someone has an easy solution.
My pages have a top menu with all level 0 pages.
I want to have a submenu on the left with all the level 1 pages below the current level 0 page.
To clarify:

topmenu: toppage1 | toppage2 | toppage3

If I am in a page below toplevel toppage1 (no matter how many levels deep!), I would need a left menu with:
childpage1fromtop1
childpage2fromtop1
childpage3fromtop1
...

Is this possible with 1 snippet on all pages (all levels deep)? Or do I need to create templates that call different snippets depending on how many levels deep the page is?
Is this possible with the wayfinder snippet?

Cheers.

Use the snippet "UltimateParent":
http://modxcms.com/extras/package/?package=475
(Sorry for being short - no time.)

Assuming your top-level documents are at root level, the Wayfinder/UltimateParent combination in your submenu will be:
NB: UltimateParent is part of the standard MODx 1.0.4 package
- you need to have the Wayfinder call [!uncached!] and UP [[cached]] for the nested snippet to work properly.

ok, thanks guys, Ottogals answer led me to http://wiki.modxcms.com/index.php/Snippet_call_anatomy where the code is mentioned that I think will do what I need.

I have been messing around with this but it is not doing what it is supposed to do. I fear the reason is that I am using revolution. Could this be?

The tag syntax is certainly different from Evo: http://rtfm.modx.com/display/revolution20/Tag+Syntax

i understand the difference in syntax, but no matter what i do i can only see the menu if I set the startid to 0.
Changing this to 2 or 3 will return an empty result.
I cannot manage to get child pages in a submenu

My site is currently built like this:
page 0
\-- page 2
\-- page 3

i am using the code from http://muddydogpaws.com/development/wayfinder/examples/example-4.html
