如何创建一个在单击下拉菜单文本形式。下面的例子中，如何将登录名（目前在导航栏中）移动到下拉菜单中，并仍然保留它在点击时的功能（但现在在下拉菜单中显示文本框和登录按钮）？

您最终可以像添加任何其他元素一样添加表单。

.navbar .dropdown-menu { 
 
    width: 300px; 
 
    padding: 10px; 
 
} 
 
.navbar .dropdown-menu { 
 
    border-radius: 0; 
 
    box-shadow: none; 
 
} 
 
.navbar .dropdown-menu form .form-group .form-control, 
 
.navbar .dropdown-menu form .form-group label, 
 
.navbar .dropdown-menu form .form-group .btn-primary { 
 
    margin: 5px 0; 
 
}
