我无法使折叠函数在Bootstrap上工作

我曾尝试用bootstrap制作一个手风琴，但由于某种原因，当我尝试使用它时，手风琴不会展开以显示内容。有人能解释一下我做错了什么吗？

<div class="accordion accordion-flush" id="accordionFlushExample">
<div class="accordion-item">
<h2 class="accordion-header" id="flush-headingOne">
<button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#flush-collapseOne" aria-expanded="false" aria-controls="flush-collapseOne">
Filters
</button>
</h2>
<div id="flush-collapseOne" class="accordion-collapse collapse" aria-labelledby="flush-headingOne" data-bs-parent="#accordionFlushExample">
<div class="accordion-body">
<ul>
<li><a href="/recipes">All Recipes</a></li>
<li><a href="/recipes?mealtype=your">My Recipes</a></li>
<li><a href="/recipes?mealtype=breakfast">Breakfast Recipes</a></li>
<li><a href="/recipes?mealtype=lunch">Lunch Recipes</a></li>
<li><a href="/recipes?mealtype=dinner">Dinner Recipes</a></li>
<li><a href="#">Vegeterian Recipes</a></li>
<li><a href="#">Vegan Recipes</a></li>
<li><a href="#">Low Calorie Recipes</a></li>
</ul>
</div>
</div>
</div>
</div>

我在网上看到的类似问题的常见解决方案指向jquery脚本没有运行，但我有以下脚本，顺序如下：

<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>

(引导程序5(

我只是用div+id包装了可折叠的部分，然后给我有collapse类的每个div一个data-bs-parent。

# radio button group
<div class="row">
<label class="col-12 col-md-8 col-form-label">
What is your choice ?
</label>
<div class="col-12 col-md-4">
<div class="btn-group btn-group-sm" role="group">
<input type="radio" class="btn-check" name="myRadio" value="yes" id="msg1"
aria-expanded="false"
aria-controls="msg1"
data-bs-toggle="collapse"
data-bs-target="#msg1">
<label class="btn btn-outline-primary" for="msg1">Msg 1</label>
<input type="radio" class="btn-check" name="myRadio" value="no" id="msg2"
aria-expanded="false"
aria-controls="msg2"
data-bs-toggle="collapse"
data-bs-target="#msg2">
<label class="btn btn-outline-primary" for="msg2">Msg 2</label>

</div>
</div>
</div>
<div class="row">
<div class="col" id="display_data">        <!-- id wrapping all collapsed divs -->
<div class="alert alert-warning collapse" id="msg1" data-bs-parent="#display_data">
<strong>Yes</strong><br>
this is msg 1
</div>
<div class="alert alert-warning collapse" id="msg2" data-bs-parent="#display_data">
<strong>No</strong><br>
this is msg 2
</div>
</div>
</div>

OP正在使用Bootstrap 的版本5

我添加了官方css&js链接。Bootstrap 5已删除jQuery依赖

您的HTML看起来不错。正如其他人所说，这里不需要jQuery。我看到你正在使用Alpha CDN，我建议使用测试版，因为它更稳定。更改JS以使用它应该是您所需要做的全部：
