The downward trajectory of the Hamburger Menu is uncompromised, yet it refuses

Currently, I am utilizing Ruby on Rails 7 and Bootstrap 5. I encountered an issue with my hamburger menu functionality - it opens successfully but fails to close. Strangely, all other dropdowns work perfectly fine. Below is the snippet of the problematic code:

<nav class="navbar navbar-expand-lg bg-dark border-bottom border-body" data-bs-theme="dark">
    <div class="container-fluid">
      <a class="navbar-brand" href="/" style="color: white">ContactPoints.io</a>
      <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>

      <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
        <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
          <% if current_user %>
            <%= render "layouts/logged_in_nav" %>
          <% else %>
            <%= render "layouts/logged_out_nav" %>
          <% end %>
        </ul>
      </div>
    </div>
  </nav>

Here are the CDNs used:

<!DOCTYPE html>
<html>
  <head>
    <title>Contact Points</title>
    <meta name="viewport" content="width=device-width,initial-scale=1">
    <%= csrf_meta_tags %>
    <%= csp_meta_tag %>
    <%= favicon_link_tag 'favicon.ico' %>

    <%= stylesheet_link_tag "application", "data-turbo-track": "reload" %>
    <%= javascript_include_tag "application", "data-turbo-track": "reload", defer: true %>
    ...

While all other Bootstrap features function correctly, only the hamburger menu presents a problem. Even after substituting with verified code from GetBootstrap, the issue persists. This indicates the issue lies elsewhere, possibly within the configuration or setup.

UPDATE: Following suggestions, I performed tests by selectively commenting out various CDNs. Surprisingly, I discovered a specific combination that resolves the menu problem:

<!-- Include Bootstrap modal library -->
<!-- <script src="https://cdn.jsdelivr.net/npm/bootstrap/dist/js/bootstrap.bundle.min.js"></script> -->

<%# javascript_include_tag "application", "data-turbo-track": "reload", defer: true %>

It appears that both the JavaScript tag and Bootstrap modal library interfere with the hamburger menu functionality. By commenting out both, the issue is resolved. However, the exact cause remains obscure.

Here is the code snippet from my application.js within javascript/controllers:

...

Is it common to have two application.js files while using hotwire? Feedback suggests that it is normal and that the existing setup seems appropriate.

Removing the conflicting line from application.js did not resolve the issue. The investigation into the root problem continues.

Answer №1

After some investigation, I managed to identify the issue.

It turns out that I inadvertently included bootstrap twice in my project.

First, I included it via the CDN in the application.html.erb file.

Then, I also imported it again through application.js.

To resolve this, I took the following steps:

  1. Disabled the bootstrap modal CDN import code as it was already included in the main bootstrap JS import.

  2. Disabled the bootstrap JS CDN import code since it was redundant due to the @import directive in the application.js file.

  3. Left the bootstrap CSS CDN as is.

By doing this, I ensured that the bootstrap JS was only imported once through the @import in the javascript_include_tag, eliminating the double import issue.

It was surprising to discover that this duplication was causing trouble with the hamburger menu functionality.

For others facing a similar problem, I recommend checking if you are inadvertently importing bootstrap through multiple methods and eliminating one of them.
