Does anybody knows how to implement expand/collapse only on icon click in collapsibe div?

Answer 1

I found following way:

...
                collapsibleHeading.find(".ui-icon").bind("click", function (event) {
                    var type = collapsibleHeading.is(".ui-collapsible-heading-collapsed") ?
                                                                                "expand" :                "collapse";

                    collapsible.trigger(type);

                    event.preventDefault();
                });

If you need more details let me know please.
