css - 如何使 Bootstrap 'List group' 响应

Question

我正在使用 Bootstrap ' List group ' 我需要让它响应。 意味着在移动 View 中，列表将显示为像导航栏一样的下拉按钮。

我试过导航类，但没有按预期工作。 代码:

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#side-menu-collapse">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
</button>    
<ul class="list-group collapse navbar-collapse" id="#side-menu-collapse">
  <li class="list-group-item dropdown-toggle">Cras justo odio</li>
  <li class="list-group-item dropdown-toggle">Dapibus ac facilisis in</li>
  <li class="list-group-item dropdown-toggle">Morbi leo risus</li>
  <li class="list-group-item dropdown-toggle">Porta ac consectetur ac</li>
  <li class="list-group-item dropdown-toggle">Vestibulum at eros</li>
</ul>

您可以通过一些媒体查询来做到这一点。当屏幕尺寸与 XS 不同时覆盖 collapse 类。

Bootstrap :https://www.bootply.com/L5BYCOwsZG

CSS:

@media screen and (min-width: 768px) {  
    .custom-collapse .collapse {
            display:block;
    }  
}

HTML:

<div class="custom-collapse">
  <button class="collapse-toggle visible-xs " type="button" data-toggle="collapse" data-parent="custom-collapse" data-target="#side-menu-collapse">
      <span class="">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
  </button> 
  <ul class="list-group collapse" id="side-menu-collapse">
    <li class="list-group-item dropdown-toggle">Cras justo odio</li>
    <li class="list-group-item dropdown-toggle">Dapibus ac facilisis in</li>
    <li class="list-group-item dropdown-toggle">Morbi leo risus</li>
    <li class="list-group-item dropdown-toggle">Porta ac consectetur ac</li>
    <li class="list-group-item dropdown-toggle">Vestibulum at eros</li>
  </ul>
</div>
