如何在 Bootstrap 中创建一个保留状态的侧边栏菜单？

Question

如果我有一个控制器 - 目的地，顶部栏菜单具有相同的名称。当我单击“目的地”顶部菜单时，我想要一个带有 Dest1、Dest2、Dest3 项目的左侧边栏，这些项目会显示/隐藏。但是，如果我选择 Dest1、Dest2 或 Dest3（它们是指向不同视图的链接），我希望侧边栏始终保持可见。到目前为止，我在 Destinations 索引视图中有这个，但我不想在下面的侧边栏菜单的每个项目中重复这个。 我还希望侧边栏项目根据选择的内容保持突出显示。顶栏菜单是在 /-Layout 视图中定义的，我应该把侧栏也放在那里吗？谢谢。

<div class="container-fluid">
    <div class="row">
        <div class="col-md-2">
            <ul class="nav  navbar-fixed-side navbar-fixed-side-left">
                <li>@Html.ActionLink("Dest1", "Dest1", "Destinations")</li>
                <li>@Html.ActionLink("Dest2", "Dest2", "Destinations")</li>
                <li>@Html.ActionLink("Dest3", "Dest3", "Destinations")</li>
            </ul>
        </div>

你可以试试下面的代码

            });
        });
