在子菜单中切换子菜单

Question

我正在尝试切换菜单中的项目。现在我有 3 个图标，当它们被点击时，点击图标下的 UL dropdown-mobile 打开。单击 'Main menu item' 时，'sub-menu item' 应滑动打开，单击 'sub-menu item' 时，'sub-sub-menu item' 应滑动打开。现在我似乎只能滑动打开 UL dropdown-mobile 但我不确定如何打开它以便切换其中的子菜单。

所以我有以下布局作为菜单：

// slideToggle for mobile mainmenu
$('li.icons-list').click(function(e) {
  if ($(this).siblings('li.hovertest').find('ul.dropdown-mobile:visible').length) {
    $('ul.dropdown-mobile').slideUp('slow');
  }
  $(this).find('ul.dropdown-mobile').slideToggle('slow'); // show the respective one.
});

Answer 1

这应该有效，您必须使用以下条件：

// slideToggle for mobile mainmenu
$('#icons-wrapper li').click(function(e) {
  var $this = $(this);
  if ($(this).children('ul:visible').length) {
    $(this).find('> ul:visible').stop().slideUp('slow');
  } else {
    $(this).children('ul').stop().slideToggle('slow');
  }
  return false;
});

ul ul {
  display: none;
}

Answer 2

如果我理解正确的话：

// slideToggle for mobile mainmenu
$('#icons-wrapper li').click(function(e) {
  e.stopPropagation();
  $(this).find('>[class*="subsubmenu-"]').slideToggle('slow');
});
