Ok, I tell you how it would work - maybe you want to try to provide that to MyFaces:
You'll need to create a new, custom tag and component (let's call it t:header) which you can add to the (t:)panel-grid. (t:header cause it will be used in t:panelGrid, and so we cannot add it to the sandbox. We'd do it with a facet, but facets accept only one child, and that's not enough in this case ;) regards, Martin On 2/3/06, Matthias Kahlau <[EMAIL PROTECTED]> wrote: > Thanks, > > but only formatting some components as headers is not sufficient in my case, > because the HTML output needs to contain structural header elements to > comply to accessibility requirements... > > > Regards, > > Matthias > > > -----Ursprüngliche Nachricht----- > > Von: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] Auftrag > > von Volker Weber > > Gesendet: Freitag, 3.
