An example explaining how to create a handle to the groupremoving event in Accordion widget.
By handling this event you can prevent removing of groups depending on some custom conditions. By returning a false value, you can cancel this event. Whenever the 'Remove Group' button is clicked the currently selected group will be removed from the Accordion, until only one groups remains.
$(document).ready(function() {
// Create an instance of Accordion widget
var $bar = $('#accordion').accordion();
// Get the group that is currently selected in Accordion
var getCurrentSelection = function(){
return $bar.accordion("option", "selectedGroup");
}
// When 'Remove Group' button is clicked, it removes the currently selected group from the Accordion
var remove = function(){
$bar.accordion("removeGroup", getCurrentSelection());
}
// Create a handler to the groupremoving event
$bar.on({
"groupremoving": function(e){
var groupCount = $bar.accordion("getList").length;
if (groupCount <= 1)
return false;
});
});
