Thanks.
Ok I will explain more, I create select element with 3 options and every option is related to a fieldset which contains(fields et) a number a radio options, so when I select an option the fieldset related to this option will be on(enable) and the other(fieldset containg the another radio options) will be off(disabled)
I want to know how could I do this?

Thanks for every single help

(one) general rout to go:
select one option (use the change event)

disable all radios/fieldset

re-enable the radios/fieldset according to the select value (you need to define somewhere, which radios/fieldset to enable. e.g. if there belongs one fieldset to one option, you can save the fieldset’s id in the option’s value)
