我需要在Bootstrap 3的下拉菜单中放置一个下拉菜单...。这是我尝试的：Demo。

在此处输入图片说明

不幸的是，当我单击第二个下拉菜单时，它没有显示。

单击时如何显示第二个下拉菜单？然后，如何（使用JS或jQuery）处理第二个下拉列表的状态更改？

HTML：

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container">
        <div>
            <ul class="nav navbar-nav">
                <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Settings<span class="caret"></span></a>

                    <ul class="dropdown-menu" role="menu">
                        <li><a href="#">Edit</a>
                        </li>
                        <li><a href="#">Delete</a>
                        </li>
                        <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Visible by friends<span class="caret"></span></a>

                            <ul class="dropdown-menu" role="menu">
                                <li><a href="#">Visible by friends</a>
                                </li>
                                <li><a href="#">Visible by me only</a>
                                </li>
                                <li><a href="#">Visible by anyone</a>
                                </li>
                            </ul>
                        </li>
                    </ul>
                </li>
            </ul>
        </div>
    </div>
</div>

您可以尝试手动触发内部模式的下拉菜单。见小提琴

Js：

$('.dropdown li').click(function (e) {
e.stopPropagation();
});
$('.dropdown-inner').click(function (e) {
    e.stopPropagation();
    $(this).toggleClass('open').trigger('shown.bs.dropdown');
});

HTML：

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
    <div>
        <ul class="nav navbar-nav">
            <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Settings<span class="caret"></span></a>

                <ul class="dropdown-menu" role="menu">
                    <li><a href="#">Edit</a>
                    </li>
                    <li><a href="#">Delete</a>
                    </li>
                    <li class="dropdown-inner"> <a href="#" class="dropdown-toggle-inner">Visible by friends<span class="caret"></span></a>

                        <ul class="dropdown-menu" role="menu">
                            <li><a href="#">Visible by friends</a>
                            </li>
                            <li><a href="#">Visible by me only</a>
                            </li>
                            <li><a href="#">Visible by anyone</a>
                            </li>
                        </ul>
                    </li>
                </ul>
            </li>
        </ul>
    </div>
</div>
