Bootstrap 5 Collapse Component Not Toggling When Nested in Cards

bootstrap-5 collapse cards HTML

I'm maintaining legacy code that I'm working through a tutorial and I keep running into I've been banging my head against this for hours... This might be a silly question, but I'm having an scenario with the Bootstrap 5 collapse component when it's nested inside Bootstrap cards. I've set up the collapse functionality, but it doesn't seem to work as expected; the toggle button doesn't open or close the collapsible content. Instead, it just refreshes the page. I'm using Bootstrap version 5.1.3 and jQuery 3.6.0. Here's a snippet of my HTML: ```html <div class="card"> <div class="card-header"> <h5 class="mb-0"> <button class="btn btn-link" data-bs-toggle="collapse" data-bs-target="#collapseExample" aria-expanded="true" aria-controls="collapseExample"> Collapsible Group Item #1 </button> </h5> </div> <div id="collapseExample" class="collapse" data-bs-parent="#accordionExample"> <div class="card-body"> Some placeholder content for the first collapse. </div> </div> </div> ``` I've ensured that I've included the necessary Bootstrap CSS and JS files in my project: ```html <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet"> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"></script> ``` I also checked if there was any JavaScript behavior in the console, but I only see a few warnings about unused CSS classes. I've tried isolating the collapse component outside of the card to see if it works independently, and it does. However, when it's inside the card, the functionality breaks. Does anyone know why this might be happening? Is there a common scenario with the collapse component when nested in card components? Any help would be greatly appreciated! I'm working on a service that needs to handle this. Has anyone else encountered this? For context: I'm using Html on Linux. What's the best practice here? This is for a web app running on macOS. What's the best practice here? Has anyone else encountered this? This is my first time working with Html 3.9. What's the best practice here?
