当其中一个部分在引导程序 4 中展开时，如何停止折叠其他部分？

Question

我有这样一架手风琴：

<div class="accordion" id="accordionExample">
       
       <!-- First -->
        <div class="card">
            
            <div class="card-header" id="headingOne">
                <h5 class="mb-0">
                    <button class="btn btn-link text-primary px-0 text-uppercase" type="button"
                            data-toggle="collapse" data-target="#collapseOne" aria-expanded="true"
                            aria-controls="collapseOne">
                        First block                        </button>
                </h5>
            </div>

            <div id="collapseOne" class="collapse " aria-labelledby="headingOne"
                 data-parent="#accordionExample">
                <div class="card-body">

                     <div class="form-check">

                    </div>

我使用 bootstrap 4 使其可折叠/可扩展。现在的行为是这样的：当我单击一个块时，它会展开，然后当我单击另一个块时，另一个块会展开，但前一个块会折叠。我想做另一种行为 - 在单击另一个块时不要折叠先前展开的块。如果有什么东西被打开了——让它保持打开状态。我怎么能用引导程序做到这一点？这是 jsfiddle - https://jsfiddle.net/dLa4p0uc/

所以最后我刚刚删除了：

data-parent="#accordionExample"

在这个例子中无处不在，这正是我所需要的。是啊
