Bootstrap导航栏下拉列表未打开

提问于

Bootstrap导航按预期折叠，但在单击汉堡包时不显示下拉 . JSFiddle示例here - 使用：bootstrap / 3.3.7 / css / bootstrap.min.css和bootstrap / 3.3.7 / js / bootstrap.min.js作为我的两个外部资源 .

我发现其他人声明按钮的数据目标需要匹配包含折叠导航的div的ID . 就我而言，data-target =“＃page-nav-tabs”和我的div id =“page-nav-tabs” . 但这仍然不起作用....请帮忙！

更新：发现折叠菜单的修复程序未打开 - 需要包含jquery脚本 . 现在，我仍然遇到“创建新”下拉列表无效的问题 .

    检查一下它现在正在工作

    或者只需更换按钮线

    <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Create New <span class="caret"></span></button>
