Ho un form per la data con tre seclect
uno per il giorno, uno per il mese e uno per l'anno.

Vorrei impostare il valore di default con il valore della data dal giorno.

inoltre vorrei che se uno setta il mese febbraio, come opzioni per il giorno abbia solo da 1 a 28 ecc..

Avete dei link che mi suggeriscano come fare?
