我正在尝试实现 Bootstrap button dropdown 。我按照文档中的说明进行操作:
<div class="btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Action <span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div>
下拉列表显示我页面上的列表项:
知道我做错了什么吗？
最佳答案
当我包含所有 boostrap 文件时工作正常，可能你错过了一些 css
