$(document).ready(function() {

  $("#accordion > li > div").click(function() {
    $("#submenu li").slideUp();
    if (!$(this).next().is(":visible")) {
      $(this).next().slideDown();
    }
  });
  
  $(".submenu li a").click(function(){
    $(".submenu li a.active").removeClass("active");
    $(this).addClass("active");
  });
});

.accordion {
  width: 100%;
  max-width: 260px;
  background: #FFF;
  margin: 0;
