Question

有没有办法让twitter引导程序中的嵌套列表看起来像普通列表，嵌套项目只是缩进（并使其适用于任意深度嵌套）？默认情况下，嵌套列表看起来像this：

Nested lists with bootstrap

<ul class="list-group">
    <li class="list-group-item">One</li>
    <li class="list-group-item">Two
        <ul class="list-group">
            <li class="list-group-item">Item 2a</li>
            <li class="list-group-item">Item 2b</li>
        </ul>
    </li>
    <li class="list-group-item">Three
        <ul class="list-group">
            <li class="list-group-item">Item 3a</li>
            <li class="list-group-item">Item 3b</li>
        </ul>
    </li>
</ul>

Answer 2

这是我的方法：

    .list-group-collapse li > ul li:first-child {
        border-top-left-radius: 0;
        border-top-right-radius: 0;
    }

    .list-group-collapse li > ul {
        margin-left: -16px;
        margin-right: -16px;
        margin-bottom: -11px;
    }

如果您使用的是BS3，那么将.list-group-collapse类添加到您的分组列表中就可以了。请参阅JSFiddle：https://jsfiddle.net/oscar_dr/d2wpn8sd/1/

当然，如果您有自定义的Bootstrap，您可以使用此类扩展BS或将值更改为自定义度量。

编辑：添加了代码片段以回答：

.list-group-collapse li>ul li:first-child {
  border-top-left-radius: 0;
  border-top-right-radius: 0;
}

.list-group-collapse li>ul {
  margin-left: -16px;
  margin-right: -16px;
  margin-bottom: -11px;
}

Answer 3

由于glyphicons不再是Bootstrap的一部分，我修改了Marcos的回答以使用Bootstrap 4（以及强大的图标）。主要变化是：

用强大的图标替换字形
将班级列表-group-item-action添加到list-group-item
在css中重新定义.collapse（也许有更好的方法）

.collapse {
    display: none;
    &.show {
        display: block;
    }
}

Bootstrap 4更新

我希望能够在Bootstrap 4中使用它。希望这对其他人有帮助。

这是使用字体棒的代码（因为V4不支持字形）。
