侧边栏导航可能非常复杂。这就是Bootstrap没有“开箱即用”组件的原因。 补充工具栏有很多注意事项 ：

• 响应式-根据屏幕宽度设置不同的宽度，可见性或方向？
• 多级-导航项是否具有子级？这个高度会受到怎样的影响？
• 可切换-边栏可以通过按钮或“汉堡包”切换吗？
• 推送与重叠-页面内容是隐藏在侧边栏的后面还是旁边？
• 左侧还是右侧-页面内容左侧还是右侧的侧边栏是？
• 固定或固定-侧边栏在页面滚动上的位置如何？
• 动画样式-向左/向右/向上/向下滑动？是否折叠？

在这种“侧边栏”情况下…而不是col-auto在右列中使用col。这样，当折叠菜单时它将填充宽度

<div class="container-fluid h-100">
  <div class="row h-100">
    <div class="col-5 col-md-3 collapse width m-0 p-0 h-100 bg-dark" id="collapseExample">
       ..
    </div>
    <div class="col">
      <div class="row">
        <div class="col-12">
          <button class="btn sticky-top" data-toggle="collapse" href="#collapseExample" role="button">
            Menu
          </button>   
        </div>
        <div class="col-12">
           ..
        </div>
      </div>
    </div>
  </div>
</div>

为了使动画更加平滑，必须覆盖Bootstrap的折叠过渡，该过渡通常在高度上起作用

编辑：

根据赏金要求，我用另外2个示例更新了侧边栏

最低版本

该版本更接近示例，并且具有相同的幻灯片左/右“抽屉”动画。

body {
    height: 100vh;
    overflow-x: hidden;
    padding-top: 56px;
}

.vh-100 {
    min-height: 100vh;
}

.sidebar.collapse.show,
.sidebar.collapse.show + .col {
    transition: .18s ease;
    transform: translate(0,0,0);
    left: 0;
}

.sidebar.collapse,
.sidebar.collapsing,
.sidebar.collapsing + .col {
    transition: .18s ease;
    transform: translate(-25%,0,0);
    z-index: 1050;
    left: -25%;
}

完整版本 （ 非常 接近：

此侧边栏具有：

• 固定宽度
• 自动关闭在小屏幕上 ， 在更广泛的屏幕打开
• 可以任意宽度打开/关闭
• 反应灵敏- 在较小宽度上 成为 固定覆盖

完整版确实需要更多CSS，但是其中一些是可选的…
