The easiest way to achieve this is to call the collapsible() method on the dynamically created divs:

$('div[data-role=collapsible]').collapsible();

source : http://forum.jquery.com/topic/dynamically-add-collapsible-div

this is what i do. Hope it helps

HTML

<div id="collapsibleSet" data-role="collapsible-set">

   <div id="ranking1"></div>

</div>

Javascript

$('#ranking1').replaceWith('<div id="ranking1" data-role="collapsible" data-collapsed="false">' + htmlRankings(ranking) + '</div>');

$('#collapsibleSet').find('div[data-role=collapsible]').collapsible({refresh:true});

htmlRankings() is a js function that returns some html that i want inside the collapsible div.
it can be something like this

<h3>11</h3>

<span>test</span>

I think

after setting the innerhtml, simply tiggerring a event on it should render the dynamic contnet like below

$('#<divId or elementId').trigger("create");

This code is for perl, you can modify it for any programming language.

 <a href="javascript:collapsible('$div_instance','$imageID')">

         <IMG id='$imageID' SRC='$imagePath' alt='(Expand / Collaspe Section' title='Expand / Collaspe' width=10 height=10>

          $display_header <br/></a>

          <div id=$div_instance name=$div_instance 

           style="overflow:hidden;display:$display_option;margin-left:30px; margin-top:20px;">

                                       <-- your content -->

            </div>

<script language="JavaScript" type="text/javascript">

    <!--

     function collapsible(theID,imageID) {

          var elemnt = document.getElementById(theID);

          var imageObject =document.getElementById(imageID);

          if(elemnt.style.display == 'block') {

               elemnt.style.display ='none';

               imageObject.src='images/expand_icon.gif';

           }

           else{

           elemnt.style.display ='block';

           imageObject.src='images/expand_icon_down.gif';

           }



    }

    // -->

    </script>

REF: http://www.ssiddique.info/simple-javascript-to-create-dynamic-collapsible-section.html

As of jquery mobile beta2 you trigger an event - .trigger('create')

you can refresh the collapsible using the following code

$('#element').collapsibleset('refresh');

Hope it helps

You have to append them to the right place (e.g. under a data-role="page" element) then call .page() to initialize the content you appended, like this:

$('<div data-role="collapsible"><h3>Title</h3><p>Content</p></div>')

  .appendTo('#someElement').page();

You can test it out here.

Better than collapsible is updatelayout, it is in the docs. In short...

This event is triggered by components within the framework that dynamically show/hide content, and is meant as a generic mechanism to notify other components that they may need to update their size or position. Within the framework, this event is fired on the component element whose content was shown/hidden, and bubbles all the way up to the document element.

$('div[data-role=collapsible]')

    .trigger( 'updatelayout' );

    //.collapsible();

This way you can add small collapsibles in a bigger one dynamically.
HTML:

<div data-role="collapsible" data-mini="false" data-theme="b"  >

    <h3>main header text</h3>

    <div id="aCollaps"></div>

</div>

Javascript

//Your could do for(){

    $("#aCollaps").append('<div data-role="collapsible" data-inset="false" data-content-theme="b">' + 

    '<h3>'+HeaderText+'</h3>'+ContentText+'<br/></div>');

//}

//You might want to be more specific here if you have more collapsibles in the page. this just updates all collapsibles

$('div[data-role=collapsible]').collapsible({refresh:true});

Here's an example of what I did to dynamically change my collapsible. I had a few arrays that I needed to display as headers, and then I needed a grid in each collapsible set with 2 sides, one for question and one for answer.

   var inputList = '';

    var count = 0;

    var divnum = 999;

    var collit = 'false';

    inputList += '<div data-role="content">';

    inputList += '<div id="fb_showings_collapse" data-role="collapsible-set" data-theme="b">';

    $.each(fbFullStrArray, function(index, item) { 

    //set questions and answers for each appt

    getsetApptFback(fbStrApptArray[index]);

    //write the html to append when done

    inputList += '<div data-role="collapsible" data-collapsed="'+collit+'">';

    inputList += '<h3>'+fbFullStrArray[index]+'</h3>';

    inputList += '<div id="g'+divnum+'" class="ui-grid-a">';

    inputList += '<div id="gb'+divnum+'" class="ui-block-a">';

    inputList += '<div id="fbq'+index+'"><ol>';

    $.each(fbQidArray, function(ind,it) {

        inputList += '<li>'+fbQuestionArray[ind]+'<b></b></li>';

    });

    inputList += '</ol></div></div>'

    inputList += '<div id="ga'+divnum+'" class="ui-block-b">';

    inputList += '<div id="fba'+index+'"><ul>';

    $.each(fbQidArray, function(ind,it){

            inputList += '<li>'+fbAnswerArray[ind]+'<b></b></li>';

    });

    inputList += '</ul></div></div></div></div>';

    collit = "true";

    divnum++;

    count++;

    });

    inputList += '</div></div>';



    $('#fb_showings_collapse [role=collapsible-set]').text('');

    $('#fb_showings_collapse [role=collapsible]').text('');

    if (count > 0) {

    $('#fb_showings_collapse [role=collapsible]').remove();

    $('#fb_showings_collapse').append(inputList).collapsibleset('refresh');

    }

    else if (count == 0){

    inputList = 'Sorry! No Showings To Show Feedback For!';

    $('#fb_showings_collapse [role=collapsible-set').remove();

    $('#fb_showings_collapse [role=collapsible]').text(inputList);

    }

See the enhanceWithin() function: jQuery Mobile docs: enhanceWithin

Call enhanceWithin on a jQuery object representing your DOM element's parent to have any jQuery Mobile features added to your HTML.

In this case:

jQuery('[data-role="collapsible"]').parent().enhanceWithin();

Note that if you are adding multiple jQuery Mobile widgets you may only want to call enhanceWithin on an ancestor such as "BODY" after adding all your dynamic HTML.

This would be a pretty good solution for this question as well: Refresh a section after adding HTML dynamically to jquery mobile
