Subterms more downwards on the page, how to do this?

Hi, I like this module and possibilities.
I am not able to get the subterms more downwards on my pages.
Preferrably under other panel-panes.

But I do not know how to do this.
I themed item-list in directory.ccs but am not able to get the subterms go down under the panel-panes.
Anyone can help with this?
See www.reizen-naar.nl/nepal for example. The subterms are called "Bezienswaardigheden"
Thanks for helping me in advance!
Greetings, Martijn
