Consistent Styling for Nested Lists with Bootstrap

htmlcsstwitter-bootstraptwitter-bootstrap-3nested-lists

提问by Marcos

Is there a way to make nested lists in twitter bootstrap look like a normal list, with the nested items simply indented (and have it work for an arbitrarily deep nesting)? By default, nested lists look like this:

有没有办法让 twitter bootstrap 中的嵌套列表看起来像一个普通的列表，嵌套的项目只是缩进的（并且它可以用于任意深度的嵌套）？默认情况下，嵌套列表如下所示：

<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>

I modified Marcos answer to work with Bootstrap 4 (and fort-awesome icons) since glyphicons are no longer part of Bootstrap. The main changes are:

由于字形不再是 Bootstrap 的一部分，我修改了 Marcos 的答案以使用 Bootstrap 4（和强大的图标）。主要变化有：

  • replace glyphicons by fort-awesome icons
  • add class list-group-item-action to list-group-item
  • redefine .collapse in css (maybe there is a better approach)
  • 用令人敬畏的图标替换字形
  • 添加类 list-group-item-action 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;
    }
}

This was my approach:

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;
    }

If you are using BS3, then adding the .list-group-collapseclass to your grouped list will do the trick. See JSFiddle: https://jsfiddle.net/oscar_dr/d2wpn8sd/1/

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即可。见JSFiddle：https://jsfiddle.net/oscar_dr/d2wpn8sd/1/

Of course, you could extend BS with this class or change the values to your custom measures if you have a customized Bootstrap.

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