Question

<div className="dropdown">
              <a
                className="dropdown-toggle d-flex align-items-center hidden-arrow"
                href="#"
                id="navbarDropdownMenuAvatar"
                role="button"
                data-mdb-toggle="dropdown"
                aria-expanded="false">
                <img
                  src="https://mdbcdn.b-cdn.net/img/new/avatars/2.webp"
                  className="rounded-circle"
                  height="50"
                  alt="Black and White Portrait of a Man"
                  loading="lazy"
                />
              </a>
              <ul
                className="dropdown-menu dropdown-menu-end"
                aria-labelledby="navbarDropdownMenuAvatar">
                <li>
                  <a className="dropdown-item" href="#">
                    My profile
                  </a>
                </li>
                <li>
                  <a className="dropdown-item" href="#">
                    Settings
                  </a>
                </li>
                <li>
                  <a className="dropdown-item" href="#">
                    Logout
                  </a>
                </li>
              </ul>
            </div>

单击图像（下拉切换）时没有任何反应。我也包含了 JS 文件，css 渲染正常，但切换不工作并且没有显示下拉项：

将data-mdb-toggle替换为data-bs-toggle
d-flex 和 d-inline-flex 在正确的位置打开菜单。
