如何在这个jquery中使用click

Question

    jQuery.noConflict();
    jQuery(document).ready(function ($) {
        var $oe_menu = $('#oe_menu');
        var $oe_menu_items = $oe_menu.children('li');
        $oe_menu_items.bind('mouseenter', function () {
            var $this = $(this);
            $this.addClass('selected');
            $this.children('div').css('z-index', '9999').stop(true, true).slideDown(300, function () {
                $(this).parent().not('.selected').children('div').hide();
            });
        }).bind('mouseleave', function () {
            $(this).children('div').hide();
            var $this = $(this);
            $this.removeClass('selected').children('div').css('z-index', '1');
        }).bind('click', function () {

上面的脚本用于控制magento网站的megamenu。在手机视图中，我需要能够单击打开菜单，然后单击以关闭它。如果可能的话，我可以用加号隐藏子类别吗？请adivce。
