Question

I want to show the first element of this folding accordion. I did some research online, but in vain

Answer 1

I don’t think you have all the HTML needed for the accordion to work unless you pasted all of the above.

The first Bootstrap docs example has the first public element:

http://twitter.github.com/bootstrap/javascript.html#collapse (These documents are for version 2.3.2, which is no longer officially supported.)

I think this is the in class that sets it as public.

 <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"> Anim pariatur cliche... </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"> Anim pariatur cliche... </div> </div> </div> </div>

Update for v4:

.show can use the .show class in a .show element to open it.

 <div class="accordion" id="accordion-parent"> <a data-toggle="collapse" href="#collapseOne"></a> <div id="collapseOne" class="collapse show" data-parent="#accordion-parent"></div> <a data-toggle="collapse" href="#collapseTwo"></a> <div id="collapseTwo" class="collapse" data-parent="#accordion-parent"></div> </div> 

Here is the same example of working with v4: Demo v4 (jsfiddle)

Bootstrap v2

If you add the .in class to .collapse , it will remain open:

 <div class="accordion-group"> <div class="accordion-heading"> <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo"> Ajout d'un nouveau fonctionnaire </a> </div> <div id="collapseTwo" class="accordion-body collapse in"> <div class="accordion-inner"> </div> </div> </div>

Here is a demo with simplified markup: http://jsfiddle.net/Sherbrow/yYuRz/2/

You need to remove style="height: 0px;" from the .collapse element if you want it to be displayed.

You can also click on the fist element.

 $("#accordion a:first").trigger("click");
