I am using collapse plugin provided by bootstrap which is a jquery simple plugin

However it collapse by default, how to modify so that the collapse item is hidden by default, only when i press the header, then the item collapse and show? Thank you

The document of the plugin, just few line so it only takes one minute

$(".collapse").collapse()({
  toggle: false,
  show: false
  });
} );

            <div class="alert alert-info" data-toggle="collapse" href="#collapse1" style="margin-bottom:0px;">                     
              Collapsible #1
                  </div>   
          <div id="collapse1" class="accordion-body collapse" style="background-color:#ffffff;">
               content1
           </div>
                           <div class="alert alert-info" data-toggle="collapse" href="#collapse2" style="margin-bottom:0px;">

For Bootstrap 3, some things have changed. The following code accomplishes your desired functionality in Bootstrap 3

If you want the panel body to show by default:

<div id="collapseOne" class="panel-collapse collapse in">

If you want the panel body to hide by default:

<div id="collapseOne" class="panel-collapse collapse">

Here is an example:

<div class="bs-example">
    <div class="panel-group" id="accordion">

          <!- Repeat For Next Panel------->
        <div class="panel panel-default">
            <div class="panel-heading">
                <h4 class="panel-title">
                    <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
                       xxxxxxxxxxxHERE IS THE HEADER CONTENTSxxxxxxxxxxxx
                    </a>
                </h4>
           </div>
               <div id="collapseOne" class="panel-collapse collapse in">
                   <div class="panel-body">
                       xxxxxxxxxxxHERE IS THE BODY CONTENTSxxxxxxxxxxxx
                   </div>
               </div> 
         </div>
            <!- Repeat For Next Panel---(but change <div id="collapseTwo")--->

     </div>
 </div>
