Twitter bootstrapのネストされたリストを通常のリストのように見せ、ネストされた項目を単純にインデントする方法はありますか?デフォルトでは、ネストされたリストは this のようになります。
<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>
これらのネストされたリストを次のように(または同様の方法で)表示するにはどうすればよいですか。

これは私のアプローチでした:
.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;
}
BS3を使用している場合は、.list-group-collapse
クラスをグループ化されたリストに追加するとうまくいきます。 JSFiddleを参照してください: https://jsfiddle.net/oscar_dr/d2wpn8sd/1/
もちろん、カスタマイズしたブートストラップがある場合は、このクラスでBSを拡張したり、カスタムメジャーに値を変更したりできます。
EDIT:回答にスニペットを追加:
.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;

グリフィコンはもはやBootstrapの一部ではないため、Bootstrap 4(および要塞アイコン)で動作するようにMarcosの回答を変更しました。主な変更点は次のとおりです。
list-group-item
に追加します.collapse {
display: none;
&.show {
display: block;
}
}

ブートストラップ4アップデート
bootstrap 4.でこれを使用できるようにしたかった。これが他の人の助けになることを願っています。
素晴らしいフォントを使用したコードは次のとおりです(グリフィコンはV4ではサポートされていないため)。
