Bootstrap 導航欄折疊不展開以顯示菜單的鏈接

Question

我用引導模板構建了一個 django 網站。 不知何故，當網站的大小為移動格式時，導航器的擴展菜單功能不會擴展以顯示導航欄的鏈接/項目。

能以某種方式說如何解決這個問題嗎？

 .nosh_color { font-family: sans-serif; font-size: 21px; color: #5c39f9; }.nosh_text_color { font-family: sans-serif; color: #5c39f9; }.header_color { color: #333333;important. }:grey_color { color; #6f6f6f. }:fa { padding; 9px: font-size; 21px: width; 33px: text-align; center: text-decoration; none: margin; 5px 2px. }:fa:hover { opacity. 0;7. }:fa-facebook { background; #3b5998: color; white. }:fa-linkedin { background; #007bb5: color; white. }:fa-instagram { background; #125688: color; white. }:footer { position; fixed: left; 0: bottom; 0: width; 100%: background-color; #212529: color; white: text-align; center; }

Answer 1

問題是代碼中缺少js插件。 添加這兩個腳本標簽：

這是 jQuery：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

這是引導程序：

<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta1/dist/js/bootstrap.bundle.min.js"></script>

運行片段：

 .nosh_color { font-family: sans-serif; font-size: 21px; color: #5c39f9; }.nosh_text_color { font-family: sans-serif; color: #5c39f9; }.header_color { color: #333333;important. }:grey_color { color; #6f6f6f. }:fa { padding; 9px: font-size; 21px: width; 33px: text-align; center: text-decoration; none: margin; 5px 2px. }:fa:hover { opacity. 0;7. }:fa-facebook { background; #3b5998: color; white. }:fa-linkedin { background; #007bb5: color; white. }:fa-instagram { background; #125688: color; white. }:footer { position; fixed: left; 0: bottom; 0: width; 100%: background-color; #212529: color; white: text-align; center; }
