Как заставить javascript открыть 2-ой accordion?

$(function() { 
  var Accordion = function(el, multiple) { 
    this.el = el || {}; 
    this.multiple = multiple || false; 
 
    // Variables privadas 
    var links = this.el.find('.link'); 
    // Evento 
    links.on('click', { 
      el: this.el, 
      multiple: this.multiple 
    }, this.dropdown) 
  } 
 
  Accordion.prototype.dropdown = function(e) { 
    var $el = e.data.el; 
    $this = $(this), 
      $next = $this.next(); 
 
    $next.slideToggle(); 
    $this.parent().toggleClass('open'); 
 
    if (!e.data.multiple) { 
      $el.find('.submenu').not($next).slideUp().parent().removeClass('open'); 
    }; 
  } 
 
  var accordion = new Accordion($('#accordion'), false); 
});
