这是我在这个网站上的第一个问题。一直在这里搜索多次,找到了我需要的几乎所有答案。
我正在使用underscores.me在wordpress网站上工作 ==> test.davidsfonds-zele.be
在左侧,您可以找到可以打开的垂直菜单,以点击子项目。
当您单击并转到所属页面时,子项目会突出显示,但您无法看到它,因为该菜单不再打开。
有没有办法让它打开?
菜单是在WordPress的管理界面中构建的,因为其他管理员(没有任何网络知识)也可以更改菜单。
我尝试了很多东西,但都没有成功。如果您有完整的其他方式,请随时学习我。我认为我使用的代码是长期的... 我使用以下方法来获得我现在拥有的东西:

答案 0 :(得分:0)
我建议您使用WordPress导航菜单中提供的CSS类。在您的情况下,您可以使用JavaScript函数在您的手风琴菜单中打开.current-menu-parent
或.current-menu-ancestor
的元素。类似下面的代码,虽然我没有测试过(因为我不能):
$('#cssmenu li.has-sub.current-menu-parent').addClass('open').children('ul').slideDown();
如果您将其放入文档准备就绪,那么应该显示特定的菜单。
