。如果你想鼠标悬停显示灰色背景就添加.list-group-item-action 类:
<template>
<div class="container mt-3">
<h2>列表组</h2>
<p>列表组+active激活+disabled禁用</p>
<div class="list-group" style="margin: 20px 0">
<a href="#" class="list-group-item list-group-item-action">item1</a>
<a href="#" class="list-group-item list-group-item-action">item3</a>
<a href="#" class="list-group-item list-group-item-action">item2</a>
</div>
</div>
</template>
移除列表边框
使用 .list-group-flush 类来删除列表的边框和圆角：
<div class="list-group list-group-flush" style="margin: 20px 0">
<a href="#" class="list-group-item list-group-item-action">item1</a>
<a href="#" class="list-group-item list-group-item-action">item3</a>
<a href="#" class="list-group-item list-group-item-action">item2</a>
</div>
水平列表组
我们可以将 .list-group-horizontal 类添加到 .list-group 类后面来创建水平列表组：
<div class="list-group list-group-horizontal" style="margin: 20px 0">
<a href="#" class="list-group-item list-group-item-action">item1</a>
<a href="#" class="list-group-item list-group-item-action">item3</a>
<a href="#" class="list-group-item list-group-item-action">item2</a>
</div>
多种颜色列表项
.list-group-item-success, list-group-item-secondary, list-group-item-info, list-group-item-warning, .list-group-item-danger, list-group-item-dark 和 list-group-item-light:
<ul class="list-group">
<li class="list-group-item list-group-item-success">成功列表项</li>
<li class="list-group-item list-group-item-secondary">次要列表项</li>
<li class="list-group-item list-group-item-info">信息列表项</li>
<li class="list-group-item list-group-item-warning">警告列表项</li>
<li class="list-group-item list-group-item-danger">危险列表项</li>
<li class="list-group-item list-group-item-primary">主要列表项</li>
<li class="list-group-item list-group-item-dark">深灰色列表项</li>
<li class="list-group-item list-group-item-light">浅色列表项</li>
</ul>
还有一个案例 要模仿写一下 这个晚点
