Fabrik 3.8.1 has been released. It is mostly bug fixes and feature enhancements, but does include two new plugins (push notifications, and the sequence element). As usual we strongly recommend testing the new release on a sandbox if your application is mission critical, and always do an Akeeba backup before updating.
Masking areas whilst ajax updates
The fabrik loader object allows you to mask of sections of the page whilst they are being updated via an Ajax request.
The loader object is found here:
to overlay on a div id="hideme":
Fabrik.loader.start('hideme', 'loading ....... ');
to show a loading overlay that covers the whole page
Fabrik.loader.start(null, 'loading msg ');
