推荐答案

使用data-parent属性:

<div class="container" id=myGroup>
    <p>
        <a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" role="button" aria-expanded="false" aria-controls="collapseExample">
            content 1
        </a>
        <button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample2" aria-expanded="false" aria-controls="collapseExample2">
            Content 2
        </button>
    </p>

    <div class="collapse" id="collapseExample" data-parent="#myGroup">
        <div class="card card-body">
            Content one here
        </div>
    </div>
    <div class="collapse" id="collapseExample2" data-parent="#myGroup">
        <div class="card card-body">
            Content 2 here
        </div>
    </div>
</div>

我将id添加到了您的容器中，还将data-parent添加到了您的内容部分中，并通过id引用了此容器.

I added the id to your container and also added the data-parent to your content sections, referencing this container through the id.
