Question

我正在尝试创建一个手风琴，其中默认情况下默认情况下一个步骤处于打开状态，其余步骤可以通过单击编辑按钮来打开。下面定义的结构。

Step 1

Hello world. Lorem ipsum.
--------------------------------------------
Step 2                                  Edit
--------------------------------------------
Step 3                                  Edit
--------------------------------------------
Step 4                                  Edit

现在，如您所见，默认情况下会显示第1步的内容。因此，如果我单击步骤2的“编辑”按钮，则应该折叠步骤1，并且应该可以看到步骤2的内容。

这是我到目前为止提出的内容。

HTML：

<h6 class="ml-3 mt-3 step-1"><a id="step-one" href="#">Step 1</a></h6>
<br style="clear:both;">
<div id="promo-code" class="mt-5 ml-3">
<p>Abc content</p>
<button type="button" class="btn btn-primary">Continue</button>
</div>

<hr class="ml-3">

<div class="mt-5 ml-3" id="promo-box">
<h6>Step 2</h6>
<p>Abc content</p>
<button type="button" class="btn btn-primary">Continue</button>
</div>

JS：

$("#promo-code").click(function(){
document.getElementById("promo-code").style.display = "none";
document.getElementById("promo-box").style.display = "block";
});

$("#step-one").click(function(){
document.getElementById("promo-code").style.display = "block";
document.getElementById("promo-box").style.display = "none";
});

CSS：

#promo-code {
font-size: 15px;
color: #02b875;
}

#promo-box {
display: none;
}

.step-1 {
margin-bottom: -30px;
}

由于您正在使用引导程序，因此这里是引导程序示例。运行此代码片段，功能几乎与您想要实现的功能相同，请根据需要进行修改。
