下拉菜单

Question

我正在使用带有标签的boostrap 4下拉菜单。这是代码 我发现此链接对于停止点击事件传播非常有用，因此下拉菜单不会在其内部点击时关闭Avoid dropdown menu close on click inside

但点击标签页不起作用。   代码：boostrap 4 tabs inside drop down menu

is there any solution or another approach so that tabs work inside drop down menu

JS

$('.dropdown-menu').on("click.bs.dropdown", function (e) { e.stopPropagation(); e.preventDefault(); });

有可能的解决方案吗？

Answer 1

最简单的方法是将其包装在Use sbt shell for build and import (required sbt 0.13.5+)内，因为表单会阻止Dropdown在点击时关闭...

另一种方法是使用jQuery来表示：

<nav>
    ...
    <li class="nav-item dropdown">
             <form>
                 <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown">
                      Dropdown link
                 </a>
                 <div class="dropdown-menu">
                     ....
                 </div>
            </form>
    </li>
    ...
</nav>
