Can we create a ajax form within a fieldset of another form?

Is this possible?

The ajax form's purpose is to serve as a selector for the main form开发者_Python百科.

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.
