[SOLVED] Emiting custom <ul>...</ul> menu HTML

Hi there,
I want to replace standard pages menubar with my own - in particular the one that is generated by NAVT plugin - because it is so flexible.

My first idea to do it was to edit the code inside of:
Style and Edit Header Area -> Configure Header area
like this:
But apparently in the above spot the function 'navt_getlist' does not exist.

My second idea was to create custom widget area like this:
And then paste PHP executable code inside of Text widget (supported by Exec-PHP plugin) placed in above new widget area.

Second approach generates lots of extra "table" code + standard widget formatting around that I envision would be difficult to style correctly.

So my question is - what would be the cleanest way to emit custom <ul>...</ul> code right after the %image without bunch of formatting around?
