this website dummie uses the jquery accordion plugin http://gonzo.uni-weimar.de/~atix5565/kim/ for now everything is ok, but their is a bug which lets disapear a div container.
try this steps first: portfolio -> installations -> then the thirdmenu appears reload page. now second step: news -> portfolio -> installations -> and now there is no thirdmenu what's wrong? or do i use the accordion the wrong way? regards peter
