如何在導航欄旁邊添加向下箭頭圖標並使頁面下拉菜單？
[英]How can I add an arrow down icon next to nav bar and make pages drop down menu?
問題描述
我想知道如何在導航欄文本“關於我”和“單位”旁邊實現向下箭頭圖標。
另外，如何使這兩頁成為下拉菜單？ 在我的代碼下面，由於我不知道如何使它們成為下拉菜單，因此我沒有使它們成為下拉菜單。

只需記住為您的jquery文件更改<script src="jquery-3.1.0.min.js"></script> 。

看來您正在使用Bootstrap，因此請嘗試使用此代碼，但是我在代碼中看不到bootstrap javascipt文件，您當然必須鏈接該文件和jQuery。
<ul class="nav nav-tabs">
...
<li role="presentation" class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">
Dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu">
...
</ul>
</li>
...
</ul>
讓我知道您是否仍然無法解決。

您還會錯過javascript文件和一些代碼...下次參考http://getbootstrap.com並嘗試閱讀所有文檔。 那里的一切都記錄得很好。
另外，如果我可以為您提供建議，請使用外部CSS文件存儲您的樣式...
