JToolBarHelper::deleteListX('delete', 'checkbox_id');
JToolBarHelper::deleteListX('remove', 'cid[]', JText::_('JCONFIRMDELETE'));This adds a toolbar button with the label "Remove" that, when clicked, will call the "remove" function in the controller and pass an array of IDs in the "cid" field. It also displays a confirmation dialog box with the message "Are you sure you want to delete these items?" before deleting the items. In both examples, the package library being used is Joomla's JToolBarHelper.
