单击图标时，是否可以将引导程序折叠更改为仅显示/展开？

Question

我正在做一种选择框，他们可以选择类别。我喜欢它，所以他们可以选择任何一个项目。要做到这一点，我需要这些项目在任何地方点击时不显示/隐藏，只有在点击+或 - 图标时才能显示/隐藏。希望这是有道理的。我试着移动数据切换=“崩溃”，以为我可以把它放在我的图标上，但它最终打破了。

.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

这是一个办法做到这一点..

（由@Justin L.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

你有每个c的标题可拉伸区域作为链接。如果你把它转换成一个div，并与链接包住你的图标，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> 

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>
