单击另一个菜单项时如何切换菜单

Question

我正在使用 Genesis Framework 开发我自己的子主题。对于我的主题，当您单击顶级菜单项时，子菜单会在菜单下方水平切换打开。现在，要关闭它，您需要单击相同的菜单选项。如果您在第一个子菜单仍处于打开状态时单击另一个菜单项，则新的子菜单会出现在它上面，从而创建一个子菜单层。

我在这里查看了多个线程，并尝试按照其他人的建议使用 e.stopPropagation();。我确定我用错了，因为它不起作用。

下面是我使用的代码：

jQuery(document).ready(function(){
    jQuery(".nav-header-left .menu-item, .nav-header-right .menu-item").removeClass("menu-open");

    jQuery(".nav-header-left .menu-item-has-children, .nav-header-right .menu-item-has-children")
    .click( function( e ){
        jQuery(this).find( 'ul.sub-menu:first' ).slideToggle( function() {
            jQuery(this).parent().toggleClass("menu-open");
        });

        if ( e.target !== this ) {
            return;
        }
    });
});

这里是一个 fiddle 显示菜单的功能：https://jsfiddle.net/mve1mrcp/15/（已经更新了几次以使其看起来更好一些）

如有任何建议，我们将不胜感激！

这是您的 fiddle 中的 JS/CSS/HTML，其中包含小的修复

jQuery(document).ready(function() {
  jQuery(".nav-header-left .menu-item, .nav-header-right .menu-item").removeClass("menu-open");

  jQuery(".nav-header-left .menu-item-has-children, .nav-header-right .menu-item-has-children")
    .click(function(e) {
      var $menuItem = jQuery(this);
      console.log($menuItem)
      var $nav = $menuItem.closest('.nav-header-left, .nav-header-right'); // get the nav parent
      var shouldClose = $menuItem.hasClass('menu-open');
      var $openMenuItem = $('.menu-open').removeClass('menu-open'); // toggle all menu items to be closed
      $openMenuItem.find('ul.sub-menu:first').hide(); // hide sub-menu
      if(!shouldClose){
        $menuItem.find('ul.sub-menu:first').slideToggle(function() {
          jQuery(this).parent().addClass("menu-open");
        });
      }
    });
    
   jQuery(document).click(function(){
    $('.menu-open').removeClass('menu-open');
   })
});
