        cela se fait avec un formulaire <form>
        ex 

        <form method="post" action="pagedetraitement.php">
           <p>
               <label for="pays">Dans quel pays habitez-vous ?</label><br />
               <select name="pays" id="pays">
                   <option value="france">France</option>
                   <option value="espagne">Espagne</option>
                   <option value="italie">Italie</option>
                   <option value="royaume-uni">Royaume-Uni</option>
                   <option value="canada">Canada</option>
                   <option value="etats-unis">États-Unis</option>
                   <option value="chine">Chine</option>
                   <option value="japon">Japon</option>
               </select>
