我正在为我的应用程序使用剃刀页面。我试图将导航菜单从上到左移动。我按照此链接how to create sidebar menu in bootstrap that stays?中提到的步骤进行操作，因为我希望我的菜单与该链接完全一致。但我无法达到结果。链接中提到了一些关于simple-sidebar.css的内容，但我想知道应该将哪些内容添加到我的剃刀页面项目中。我应该做什么更改将导航菜单从上到左移动，如我提到的链接所示，因为它不适用于我的剃刀页面项目？由于我是剃刀页面的新手，因此详细说明非常有用。我的“_Layout.cshtml”中的代码如下所示。请帮我解决这个问题。

simple-sidebar.css复制到https://github.com/BlackrockDigital/startbootstrap-simple-sidebar。现在你可以在布局中添加一个链接：
official site
simple-sidebar.css是一个死的简单css lib，它只需要传统方式的html结构。
wwwroot/lib/simple-sidebar/css/simple-sidebar.css并添加一个<link rel="stylesheet" href="~/lib/simple-sidebar/css/simple-sidebar.css">
以显示导航按钮和左侧：
simple-sidebar最后，要切换侧边栏，绑定一个函数来处理事件：
<!-- your nav on top -->
<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<a asp-page="/Index" class="navbar-brand">Home</a>
<a asp-page="/Pinpad" class="navbar-brand">Pinpad</a>
</div>
</div>
</nav>
<div id="wrapper" class="toggled">
<!-- you nav on left side -->
<div id="sidebar-wrapper">
<a id="menu-toggle" href="#menu-toggle" class="btn btn-secondary">三</a>
<ul class="sidebar-nav"style="margin-top:15px;">
<li class="sidebar-brand">
<a asp-page="/Index" class="navbar-brand">Home</a>
</li>
<li>
<a asp-page="/Pinpad" class="navbar-brand">Pinpad</a>
</li>
</ul>
</div>
<!-- your main body here -->
<div id="page-content-wrapper">
<div class="container-fluid">
@RenderBody()
</div>
<footer></footer>
