Question

我创建了一个简单的MVC Net Core默认项目。我做了一些调整，使它看起来很生动。现在_Layout.cshtml仅具有顶部导航栏。

我想添加Left导航栏，在这里阅读资源。 how to create sidebar menu in bootstrap that stays?。我将其放在下面的cshtml文件中的什么位置？我尝试在下面的区域周围放置，但无法正常工作。

<div class="container body-content">
@RenderBody() area,

在下面的cshtml中，我将Navbar代码片段放在哪里？每当我放置它时，它都会对齐。

Answer 1

这是侧面菜单的bootstrap 4代码。只需使用给定的代码编辑layout.cshtml。

        $("#menu-toggle").click(function (e) {
            e.preventDefault();
            $("#wrapper").toggleClass("toggled");
        });

body {
      overflow-x: hidden;
    }

    #wrapper {
      padding-left: 0;
      -webkit-transition: all 0.5s ease;
      -moz-transition: all 0.5s ease;
      -o-transition: all 0.5s ease;
      transition: all 0.5s ease;
    }

    #wrapper.toggled {
      padding-left: 250px;
    }

    #sidebar-wrapper {
