splitting a menu-/navigation-block

[Belletage]

Hi,
when I´ve a menue-tree with about 10 items,
I can publish them with that code on one place:

Code:

<ul><?php get_i18n_navigation(return_page_slug(FALSE),0,3); ?></ul>

but when I want to place them on three places?

Its possible to slitt this "menue-line"?

f.e. in
menue-items
<ul>1-2-3</ul>
<ul>4-5-6</ul>
<ul>7-8-9-10</ul>

thanx for hints,
Bell.
