Question

我有一个操作Bootstrap选项卡面板的多级菜单，有点像C＃中的TabControl。

我遇到这个问题很困难，因为当选择一个新菜单时，菜单项不会被取消，然后再次无法选择该项目。
它类似于这篇文章： Bootstrap 4: dropdown tab items can only be selected once

我尝试了解决方法并且它不起作用，事实上，它永远不会被解雇。不知道我做错了什么。

不确定这是否正确，但这可以解决问题：

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
     // gets activated tab
    var target = $(e.target).attr("href");
    // remove active from all other menu items
    $(".nav li").removeClass("active");
    // set active for current menu item
    $('a[href="' + target + '"]').parent('li').addClass('active');
});
