以下是一个响应式HTML导航栏下拉菜单的示例代码： ```html <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script> </head> <body> <nav class="navbar navbar-default"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">Logo</a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li class="dropdown"> <a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#">Submenu 1</a></li> <li><a href="#">Submenu 2</a></li> <li><a href="#">Submenu 3</a></li> </ul> </li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </div> </nav> </body> </html> ``` 这段代码使用了Bootstrap框架来实现响应式导航栏和下拉菜单。在导航栏中，当屏幕宽度较小时，会显示一个折叠按钮，点击按钮后下拉菜单会展开。你可以根据需要修改菜单项和链接。
