我正在尝试按照引导按钮下拉菜单进行操作，但不起作用。

<div class="dropdown" style="display: block;">
    <ul class="dropdown-menu">

    <ul class="dropdown-menu">

除了缺少>如果不是拼写错误之外，您不包括用于切换菜单的下拉按钮。

例如

<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">
  Dropdown Example <span class="caret"></span>
</button>

因此，将其放在您当前的代码中：

<div class="dropdown" style="display: block;">
    <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">
      Dropdown Example <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li><a href="#" tabindex="-1">Walter</a></li>
        <li><a href="#" tabindex="-1">Bunny</a></li>
        <li><a href="#" tabindex="-1">Big Lewaoaski</a></li>
    </ul>
</div>
