Question

感谢您的帮助。

此解决方案最接近，但默认图标状态错误： Bootstrap 3 Accordion vs jquery UI accordion 和 Bootstrap 3 Collapse show state with Chevron icon 和 http://jsfiddle.net/arunpjohny/p84nw/

需要折叠所有面板的默认状态，并使用正确的折叠图标。下面的代码导致顶部手风琴面板扩展，但所有图标显示＆＃34;扩展＆＃34;州。

我尝试了一些.js来添加/删除课程，但没有运气。还使用.panel-default，no-go。

CSS：

.panel-heading .accordion-toggle:after {      
    /* symbol for "opening" panels */        
    font-family:'Glyphicons Halflings';
    content:"\e114";
    float: left;
    padding-right: 10px;
    color: grey;
}
.panel-heading .accordion-toggle.collapsed:after {    
    /* symbol for "collapsed" panels */    
    content:"\e080";
}

HTML：

<div class="panel-group" id="accordion">
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title">
                <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseOne"> 
                    Collapsible Group Item #1
                </a>
            </h4>
        </div>
        <div id="collapseOne" class="panel-collapse collapse in">
            <div class="panel-body">

            </div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading">
            <h4 class="panel-title">
                <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
                    Collapsible Group Item #2
                </a>
            </h4>

Answer 1

几年后想念你。在我今天工作的项目中遇到了类似的问题。通过添加“折叠”来解决这个问题。 class进入面板标题并稍微改变CSS。它也可以工作，以便可以在任何地方单击面板标题并触发面板动画。最后，使用span而不是锚，方式不那么凌乱。似乎对我有用。希望这可以帮助任何遇到与我一样的问题的人。

PANEL：

    <div class="panel panel-default">
    <div class="panel-heading collapsed" data-toggle="collapse" data-target="#collapseOne"> /*FIX HERE*/
        <h4 class="panel-title">
            <span class="accordion-toggle"> 
                Collapsible Group Item #1
            </span>
        </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse"> /* REMOVED 'in'*/
        <div class="panel-body">
            Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. .
        </div>
    </div>
</div>

CSS：

     .panel-heading .accordion-toggle:after {
        font-family: 'Glyphicons Halflings'; 
        content: "\e114"; 
        float: right;
        color: #ffffff;
    }
    .panel-heading.collapsed .accordion-toggle:after{ /*2ND FIX HERE*/
        font-family: 'Glyphicons Halflings'; 
        content: "\e080"; 
        float: right; 
        color: #ffffff;
    }

Answer 2

JSFiddle解决方案here：）

你犯了一些错误：

CSS选择不好，
您应该使用：在伪类之前而不是：之后
您需要在第一次崩溃中删除课程

您需要在折叠时添加折叠的类。

.panel-heading.accordion-toggle:before {           
/* symbol for "opening" panels */

font-family:'Glyphicons Halflings';
content:"\e114";
float: left;
padding-right: 10px;
color: grey;
}

.panel-heading.accordion-toggle.collapsed:before {         
/* symbol for "collapsed" panels */    

 content:"\e080";
}
