Has anyone successfully implemnted tabbed panels with wicket within brXM13?

Hello community :slight_smile:
I’m trying to get tabs on brXM cms-doctype. My crashing point is getting more than one panel to the layout (as each tab needs its own wicket:panel to put fields and compounds to it)

As I tried to wrap my brain around several tutorials or examples for wicket, it seams I need to write some java-code for it. But… is brXM taking this code? And how is it supposed to be done?
