Another option is to:
- attach a AjaxFallbackLink to the arrow,
- override the onClick method,
- in the method replace the component you want to hide with the one you
want to show:
compToHide.replaceWith(compToShow);
- then finish the method with:
if (target != null) { target.addComponent(compToShow); }
You now have changed the page structure. Upon the re-render the new
component is displayed (non-ajax browser). But in the last step you
enable an Ajaxified replace as well.
I recently wrote an article about this on my blog:

Have fun,
Erik.
