that's the definition of list and the button :

Ajouter au panier

and now this is the javascript code :

 function GetValues() {
                debugger;
                var myList = $("#multiSelect");
                var yy = $("#idtext2").val();

                var Selectedelement = $("#idtext").val();

                myList.append('<option value=' + Selectedelement + '>' + Selectedelement + " " + yy + '</option>');
                global.push({ "id": yy, "qte": Selectedelement });

            }
