Prevent Bootstrap 5 Accordion from collapsing

I'm using Bootstrap 5's Accordion component. Good news: it works perfectly well!
But the button for collapse the accordion is big, so I want to add an additional link in it, for some extra stuff.
<div class="accordion accordion-flush" id="myaccordion">
<div class="accordion-item">
<!-- important part starts here -->
<button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapse-001" aria-expanded="false" aria-controls="collapse-001">
<img src="https://picsum.photos/50/50" alt="such a nice pic"/>
<p>Sneak peek of what will appear</p>
Let's go
<button>
<!-- important part is over -->
<div id="collapse-001" class="accordion-collapse collapse" aria-labelledby="heading-001" data-bs-parent="#myaccordion">
<div class="accordion-body">
<p>Hidden stuff goes here</p>
</div>
</div>
</div>
<div class="accordion-item">
...
</div>
</div>
What I want : Clicking anywhere in the button will open the accordion, but not if I click on the link. If I click on the link, I want to follow the href.
What I get : Clicking anywhere in the button will open the accordion, even if I click on the link.
I tried to add an extra e.preventDefault() or e.stopPropagation() on the link, without success :(
Any idea?

I tried nesting the anchor inside the button but it won't work. The click event is always catched at the button level.
I didn't check bootstrap source code to check for alternatives but found a way to achieve what you asked using the following method: puth both the button and the link as children of a div and tweak with css to keep it visually on the same "line".
<h2 class="accordion-header" id="headingOne">
<div class="d-flex">
<div class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
Accordion Item #1
</div>
<a class="outlink" href="https://pullman.clubify.cl">Let's go</a>
</div>
</h2>

bootstrap accordion does not rendering markup correctly

I have the following code,
<div class="panel panel-default">
<a class="panel-heading visible-xs-block visible-sm-block visible-md-block visible-lg-block" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
<h4 class="text-danger">
Urgent
</h4>
</a>
<div id="collapseOne" class="panel-collapse collapse in">
<div class="panel-body">
some text here
</div>
</div>
</div>
The problem is that when I run the above code the accordion title (a element) does not render correctly.
Notice that the <a> does not contain any text and instead of placing my <h4> inside of the <a> it places it outside and creates an entire new element.
I will note that the page the accordion is on is being rerendered, Salesforce reRender. The page renders correctly and this is the only issue that I am having.
Can anyone tell what I am doing wrong or how to fix this? It can be a hacky fix as long as it does fix the markup.

Bootstrap - Cant get my Accordion to stay closed on default?

I have a single accordion item that I am using for a read more / less link on a page.
The purpose of this is to click it to read more, and a few paragraphs will follow.
I have this working, but I need it to stay closed when the page loads, at the moment the page loads with the item open.
What can I add to fix this?
<div class="accordionMod panel-group">
<div class="accordion-item">
<h4 class="accordion-toggle">Read More / Less</h4>
<section class="accordion-inner panel-body">
<p>more info.</p>
<h4 class="title">More titles</h4>
<p>more content</p>
</section>
</div>
</div>

I think this will work
<div class="accordion" id="myAccordion">
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#myAccordion" href="#collapseOne">
Title
</a>
</div>
<div id="collapseOne" class="accordion-body collapse">
<div class="accordion-inner">
Content
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#myAccordion" href="#collapseTwo">
Title
</a>
</div>
<div id="collapseTwo" class="accordion-body collapse">
<div class="accordion-inner">
Content
</div>
</div>
</div>
</div>
if you add the class in to accordion-body collapse it will be open by default.

Sounds like you don't need an accordion, which has multiple panels, only one of which can open at a time. Instead, just use collapse which allows you to toggle the visibility of a section of the page.
Panel Visibility
From the collapse docs:
The collapse plugin utilizes a few classes to handle the heavy lifting:
.collapse hides the content
.collapse.in shows the content
.collapsing is added when the transition starts, and removed when it finishes
Thus, to start off collapsed, just make sure your extra content has the class collapse and not in
Simple HTML
To use collapse, you really just need to specify a data-toggle="collapse" and then point the collapse to the css selector of the section you would like to toggle using data-target.
Here's a bare bones example that just exposes the collapsing functionality:
<a data-toggle="collapse" data-target="#ReadMoreInfo" href="#">
Read More / Less
</a>
<div id="ReadMoreInfo" class="collapse">
<p> More Info Here </p>
</div>
HTML with Bootstrap classes
All the other bootstrap classes are just to help make the collapsible panel look like a collapsible panel. I would recommend formatting them like this or doing a lot of custom CSS work. Even if you wanted to do the CSS yourself, starting off with this template and then overriding the styles would be best.
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse"
data-target="#ReadMoreInfo"
href="#ReadMoreInfo">
Read More / Less
</a>
</h4>
</div>
<div id="ReadMoreInfo" class="panel-collapse collapse">
<div class="panel-body">
<p>more info.</p>
<h4 class="title">More titles</h4>
<p>more content</p>
</div>
</div>
</div>
Working Demo in jsFiddle
Screenshot:

Removing the in class did not work for me in my case(though normally it should). I was just looking for the answer to this question yesterday. I used this to make the accordion default to close:
$( document ).ready(function() {
$('.collapse').collapse({
toggle: false
});
});
See also this question on:
Jquery accordion not collapse by default

if accordion is with icon, add collapsed class name to :
<a class="accordion-toggle accordion-toggle-styled collapsed" >
and add collapse class name to:
<div id="collapse0" class="panel-collaps collapse">
complete code is:
<div class="panel-group accordion" id="accordion0">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a class="accordion-toggle accordion-toggle-styled collapsed" data-toggle="collapse" data-parent="#accordion0" href="#collapse0">
Collapsible Header Text
</a>
</h4>
</div>
<div id="collapse_3_1" class="panel-collaps collapse">
<div class="panel-body">
<p> body text
</p>
</div>
</div>
</div>
</div>

It's easy. In Bootstrap 5, edit your HTML to remove the "show" class from your first accordion item. See Make accordion closed by default in Bootstrap, the answer that starts "Was recently working with Bootstrap".

Bootstrap Accordion Refresh Settings

I have a bootstrap accordion in my web app using the code found in the bootstrap documentation:
<div class="accordion" id="accordion2">
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">Section 1</a>
</div>
<div id="collapseOne" class="accordion-body collapse in">
<div class="accordion-inner">
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">Section 2</a>
</div>
<div id="collapseTwo" class="accordion-body collapse">
<div class="accordion-inner">
</div>
</div>
</div>
</div>
In my application.html.erb file I have a line of code set to refresh the page every 30 seconds.
<meta http-equiv="refresh" content="30" >
When the page refreshes it always opens up with the first section open. Is there a way to refactor the code so when the page refreshes it will stay the way the page was before the refresh?

Realized the solution is pretty simple, by changing this line of code:
<div id="collapseTwo" class="accordion-body collapse">
to this:
<div id="collapseTwo" class="accordion-body collapse in">
the section will stay open when the page is refreshed

There is, but it will be complex. The complexity lies in retaining the page state the user has created during their interactions.
Each interaction which changes the state of the GUI is going to need to be tracked so that, after 30 seconds, when the page refreshes it will be clear what the current state is.
In order to maintain the state through the page load you are going to have to use local storage in order to save the data that you collected during the interactions.
Implementing this feature as a whole will not be a trivial undertaking.

Bootstrap collapse with just one element shown

I'm trying to use the collapse components of Bootstrap.
It works well but I noticed that sometimes it doesn't close all the other elements; when I click in order from the first to the third and then back to the first again, the third one remains open.
My markup is the same as the example code that Bootstrap provides, because I'm just testing for now.
<div class="accordion" id="accordion2">
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
Collapsible Group Item #1
</a>
</div>
<div id="collapseOne" class="accordion-body collapse in">
<div class="accordion-inner">
Part 1
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
Collapsible Group Item #2
</a>
</div>
<div id="collapseTwo" class="accordion-body collapse">
<div class="accordion-inner">
Part 2
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseThree">
Collapsible Group Item #3
</a>
</div>
<div id="collapseThree" class="accordion-body collapse">
<div class="accordion-inner">
Part 3
</div>
</div>
</div>
The JavaScript code is this:
$(".collapse").collapse("#accordion2");
Considering that I'm thinking to use this components in a menu, in order to show a group open according to a PHP variable value do I just have to print the class in to the div collapseOne/collapseTwo and so on?

You do not need the javascript part, in fact - remove it!! It is that code precisely that causes the strange behaviour - accordion2 is initialized twice resulting in a double set of "logic". Your problem is fully reproduceable by using either the javascript or not.
Generally, regarding twitter bootstrap, when you can place all your data and binding-functionality in data attributes, as you have done here, you'll never have to do javascript. TB does the job automatically when the page is loading, by looking for those data attributes.
Consider javascript as a second option, an alternate way, when you cant do what you want by simply adressing the data attributes.

If you made your markup according to bootstrap collapse docs you can achieve this with the following jQuery code:
$(document).on('click', '.accordion-toggle', function(e) {
event.preventDefault();
$('#accordion2').find('.accordion-body').collapse('hide');
$(this).parent().next().collapse('show');
});
