最近,我开始了web开发,我正在使用bootstrap v5.0来构建一个网站。以下是名为";grage.php";的文件代码,代码如下:

<!-- HERE SHOULD BE THE CODE OF GARAGE    -->
<div class="container-fluid">
    <div class="row">
        <!-- CODE FOR OPTIONS-->
        <div class="col-3" style="align-items: center;">
            <div class="dropdown">
                <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
                    Dropdown button
                </button>
                <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
                    <li><a class="dropdown-item" href="#">Action</a></li>
                    <li><a class="dropdown-item" href="#">Another action</a></li>
                    <li><a class="dropdown-item" href="#">Something else here</a></li>
                </ul>
            </div>
        </div>
        <!-- CODE FOR DISPLAYING MODEL -->
        <div class="col-7">
            <div style="align-items: center;">

                </model-viewer>
            </div>
        </div>
        <!-- CODE FOR DISPLAYING CHOOSED OPTION'S AND ETC-->
        <div class="col-2">

我遇到问题,因为下拉功能不工作,如下所示,Dropdown Image

注意:我已在标题中添加了引导CSS CDN链接。

请告诉我如何解决此问题。

推荐答案

我使用的是Bootstrap V5.0

但您已加载引导数据库4。这就是它无法工作的原因。引导4使用data-toggle="dropdown",引导5使用data-bs-toggle="dropdown"。因此,请选择正确的JavaScript/CSS。

引导4示例:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.1/dist/css/bootstrap.min.css" integrity="sha384-zCbKRCUGaJDkqS1kPbPd7TveP5iyJE0EjAuZQTgFLD2ylzuqKfdKlfG/eSrtxUkn" crossorigin="anonymous">

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-toggle="dropdown" aria-expanded="false">
            Dropdown button
        </button>
  <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1">
    <li><a class="dropdown-item" href="#">Action</a></li>
    <li><a class="dropdown-item" href="#">Another action</a></li>
    <li><a class="dropdown-item" href="#">Something else here</a></li>
  </ul>
</div>

<script src="https://cdn.jsdelivr.net/npm/jquery@3.5.1/dist/jquery.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
