splitting description into multiple containers

Hi, I need to render multiple fieldsets for a model. My idea was to split up descriptions into multiple groups, assign each of the group to a MAContainer and add the containers into a root container. Something like this: MAPriorityContainer MAContainer MAStringDescription MAStringDescription MAContainer MAStringDescription MAStringDescription So I would be able to render a fieldset per container. As containers have labels I could even render a legend tag for the fieldsets. But I wasn't very lucky to do so. Is this a conceptional problem? I tried MAContainer new and setting an accessor as well as self description copy setChildren to get a container. But no luck. Any help is appreciated. thanks, Norbert
