Href到div上同样不起作用

Question

我的问题是我有一个<a href="#"> </a>标记，我无法转到div并添加inactive课程，然后当我选择另一个<a href="#"> </a>时，我可以＆＃ 39;从首先选择的div中删除inactive类，然后我就不能在href div中包含的单击id上设置它。是否有js或jquery可以处理这个？

这是我的代码（href标签）：

<div id="MainMenu">
    <div class="list-group panel">
        <a href="#demo1" class="list-group-item list-group-item-info" data-toggle="collapse" data-parent="#MainMenu">Orari Bus Italia </a>
        <div class="collapse" id="demo1">
            <a href="#dropdown1" class="list-group-item">A2 CHIAVENNA - COLICO</a>
            <a href="#dropdown2" class="list-group-item">A3 CHIAVENNA - GORDONA - SAMOLACO</a>
            <a href="#dropdown7" class="list-group-item">A4 CHIAVENNA - CAMPODOLCINO - MADESIMO</a>
            <a href="#dropdown9" class="list-group-item">A6 CHIAVENNA - OLMO</a>
        </div>
        <a href="#demo2" class="list-group-item list-group-item-info" data-toggle="collapse" data-parent="#MainMenu">Orari Bus St. Moriz </a>
        <div class="collapse" id="demo2">
            <a href="#dropdown3" class="list-group-item">Orari Autopostale Svizzero da Chiavenna a St.Moritz</a>
            <a href="#dropdown4" class="list-group-item">Orari Autopostale Svizzero da Chiavenna a Lugano</a>
        </div>
        <a href="#demo3" class="list-group-item list-group-item-info" data-toggle="collapse" data-parent="#MainMenu">Orari Treni </a>
        <div class="collapse" id="demo3">
            <a href="#dropdown5" class="list-group-item">Orari Treni - Chiavenna - Milano</a>
            <a href="#dropdown6" class="list-group-item">Orari Treni - Chiavenna - Sondrio</a>
        </div>
        <a href="#demo4" class="list-group-item list-group-item-info" data-toggle="collapse" data-parent="#MainMenu">Informazioni Turistiche</a>
        <div class="collapse" id="demo4">
            <a href="#sectionB" class="list-group-item">Informazioni turistiche</a>
        </div>
    </div>
</div>

然后，这里有我上面链接的div标签：

<div class="tab-content">
