css - Bootstrap 2 列选项卡

Question

我想制作一个 nav-tabs ul 以 2 列而不是水平方式呈现其内容(这是 bootstrap nav-tabs 的默认样式)。

我尝试了 css 属性 column-count: 2 但它不起作用

下面是我的代码

<ul class="nav nav-tabs ml-0 mr-0 bg-primary two-columns" role="tablist" style="column-count: 2;">
    <li class="nav-item"><a class="nav-link active" data-toggle="tab" href="#cont1"  role="tab">Title 1</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont2"  role="tab">Title 2</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont3"  role="tab">Title 3</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont4"  role="tab">Title 4</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont5"  role="tab">Title 5</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont6"  role="tab">Title 6</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont7"  role="tab">Title 7</a></li>
    <li class="nav-item"><a class="nav-link       " data-toggle="tab" href="#cont8"  role="tab">Title 8</a></li>
</ul>


<!-- Tab panes -->
<div class="tab-content ml-2 mr-2">
    <div class="tab-pane jumbotron active" id="cont1" role="tabpanel">Conctent 1</div>
    <div class="tab-pane jumbotron active" id="cont2" role="tabpanel">Conctent 2</div>
    <div class="tab-pane jumbotron active" id="cont3" role="tabpanel">Conctent 3</div>
    <div class="tab-pane jumbotron active" id="cont4" role="tabpanel">Conctent 4</div>
    <div class="tab-pane jumbotron active" id="cont5" role="tabpanel">Conctent 5</div>
    <div class="tab-pane jumbotron active" id="cont6" role="tabpanel">Conctent 6</div>
    <div class="tab-pane jumbotron active" id="cont7" role="tabpanel">Conctent 7</div>
    <div class="tab-pane jumbotron active" id="cont8" role="tabpanel">Conctent 8</div>
</div>

和我的自定义 css 类 双列

ul.two-columns {
    -moz-column-count: 2 !important;
    -moz-column-gap: 2.5em !important;
    -webkit-column-count: 2 !important;
    -webkit-column-gap: 2.5em !important;
    column-count: 2 !important;
    column-gap: 2.5em !important;
}

我想 Bootstrap 中包含的 JavaScript 会阻止我的自定义样式。下面是我的代码

有没有人知道如何实现这一点？
