我可以将单击图标时 bootstrap 折叠更改为仅 show/expand 吗？

Question

我正在制作一种 select 框，他们可以在其中选择类别。我想要它，这样他们就可以选择任何项目。为此，我需要这些项目在单击任何地方时不 show/hide，仅在单击 + 或 - 图标时。希望这是有道理的。我尝试移动 data-toggle="collapse" 以为我可以把它放在我的图标上，但它最终坏了。

.list-group.list-group-root {
    padding: 0;
    overflow: hidden;
}

.list-group.list-group-root .list-group {
    margin-bottom: 0;
}

.list-group.list-group-root .list-group-item {
    border-radius: 0;
    border-width: 1px 0 0 0;
    font-size: 18px;
}

.list-group.list-group-root > .list-group-item:first-child {
    border-top-width: 0;
}

.list-group.list-group-root > .list-group > .list-group-item {
    padding-left: 30px;
    font-size: 16px;
}

.list-group.list-group-root > .list-group > .list-group > .list-group-item {
    padding-left: 45px;
    font-size: 14px;
}

.list-group-item .glyphicon {
    margin-right: 5px;
}

Answer 1

这是一种方法..

（如@Justin L. 所解释）

.list-group.list-group-root {
    padding: 0;
    overflow: hidden;
}

.list-group.list-group-root .list-group {
    margin-bottom: 0;
}

.list-group.list-group-root .list-group-item {
    border-radius: 0;
    border-width: 1px 0 0 0;
    font-size: 18px;
}

.list-group.list-group-root > .list-group-item:first-child {
    border-top-width: 0;
}

.list-group.list-group-root > .list-group > .list-group-item {
    padding-left: 30px;
    font-size: 16px;
}

.list-group.list-group-root > .list-group > .list-group > .list-group-item {
    padding-left: 45px;
    font-size: 14px;
}

.list-group-item .glyphicon {
    margin-right: 5px;
}

Answer 2

每个可折叠区域的 header 作为 link。如果你把它变成 div，并用 link 包裹你的图标，你会得到想要的结果：

之前

<a href="#item-1" class="list-group-item" data-toggle="collapse">
    <i class="fa fa-plus pull-right"></i>Item 1
</a>

之后

<div class="list-group-item">
    <a href="#item-1" data-toggle="collapse"><i class="fa fa-plus pull-right"></i></a>Item 1
</div>

我可以将单击图标时 bootstrap 折叠更改为仅 show/expand 吗？

Can I change bootstrap collapse to only show/expand when clicking an icon?

javascript

jquery

collapse

twitter-bootstrap
