Let your panel have an onSubmit method, and let your form delegate calls to its onSubmit to the panels onSubmit. What do you mean by 'extend the form'? add more form fields? that doesn't work like this, because you have to match the panel's markup. you could use some kind of repeater or listview and generate your form fields dynamically, using data from your panel's subclass.
