[Zope] dtml-tree without frames?

Hi, I would like to create an interface and not use frames. (I would like to make my site accesible to lynx users too ";-). At this point I have a dtml-tree at the left, and some content on the right. Pretty standard like to Zope interface itself. But I would like to use the same look and feel without frames. Has anyone archieved this? TIA, Reinoud
