JQuery-Mobile collapsible slideDown effect

Question

I want to add a slideDown or slideUp effect to a div with data-role='collapsible', so it will not open at once but gradually.

I have tried this:

$('#my-collapsible').live('expand', function() {      
    $('#my-collapsible .ui-collapsible-content').slideDown(2000);
});    
$('#my-collapsible').live('collapse', function() {
    $('#my-collapsible .ui-collapsible-content').slideUp(2000);
});

But it still opens and closes without delay.

Anyone knows how should I call those slideDown and slideUp methods?

Live Example:

• http://jsfiddle.net/6txWy/6/
• http://jsfiddle.net/6txWy/7/

JS

$('#my-collaspible').bind('expand', function () {
    $(this).children().slideDown(2000);
}).bind('collapse', function () {
    $(this).children().next().slideUp(2000);
});

HTML

<div data-role="page">
    <div data-role="content">
        <div data-role="collapsible" id="my-collaspible">
            <h3>My Title</h3>
            <p>My Body</p>
        </div>
    </div>
</div>

For some reason Phill's solution didn't work in my environment, but a slightly modified version did, maybe someone will have usage of this:

$(document).on('expand', '.ui-collapsible', function() {
    $(this).children().next().hide();
    $(this).children().next().slideDown(200);
})

$(document).on('collapse', '.ui-collapsible', function() {
    $(this).children().next().slideUp(200);
});

this also works directly on all collapsible elements in jquery mobile because it uses the .ui-collapsible selector, which all collapsible elements have

Maybe an old question, but jQuery Mobile changed a lot since then.

Here is a working example on animating a collapsible set: http://jsfiddle.net/jerone/gsNzT/

/*\
Animate collapsible set;
\*/
$(document).one("pagebeforechange", function () {

    // animation speed;
    var animationSpeed = 200;

    function animateCollapsibleSet(elm) {

        // can attach events only one time, otherwise we create infinity loop;
        elm.one("expand", function () {

            // hide the other collapsibles first;
            $(this).parent().find(".ui-collapsible-content").not(".ui-collapsible-content-collapsed").trigger("collapse");

            // animate show on collapsible;
            $(this).find(".ui-collapsible-content").slideDown(animationSpeed, function () {

                // trigger original event and attach the animation again;
                animateCollapsibleSet($(this).parent().trigger("expand"));
            });

            // we do our own call to the original event;
            return false;
        }).one("collapse", function () {

            // animate hide on collapsible;
            $(this).find(".ui-collapsible-content").slideUp(animationSpeed, function () {

                // trigger original event;
                $(this).parent().trigger("collapse");
            });

            // we do our own call to the original event;
            return false;
        });
    }

    // init;
    animateCollapsibleSet($("[data-role='collapsible-set'] > [data-role='collapsible']"));
});

Here is my swing which I needed for nested stuff.

 // look for the ui-collapsible-content and collapse that
 // also need the event (which is an arg) to stop the outer expander from taking action. 
 $(document).on('expand', '.ui-collapsible', function(event) {
     var contentDiv = $(this).children('.ui-collapsible-content');
     contentDiv.hide();
     contentDiv.slideDown(300);
     event.stopPropagation(); // don't bubble up
 })

 $(document).on('collapse', '.ui-collapsible', function(event) {
         var contentDiv = $(this).children('.ui-collapsible-content');
         contentDiv.slideUp(300);
     event.stopPropagation(); // don't bubble up
 });
