i'm working now on the problem with the hidden box until the content is ready
i think with this:
http://developer.yahoo.com/yui/examp...nt-timing.html it shouldn't be a problem
at momemt i have add this: style="visibility:hidden" id="treenavi" to my navi part
and in the script i add this: fetch_object('treenavi').style.visibility = 'visible'; but it is still fired befor it is realy ready*g*
