The ajax form's purpose is to serve as a selector for the main form.

Forms cannot be nested.
Btw, you don't need a form for that purpose. Just send AJAX request without any form.
Put a select/set of radio buttons outside the form, assign onchange
handler and in it do whatever you want. For example - send AJAX query and modify the form.
