Every time a page reloads to submit a form, a puppy dies. This plugin is the saviour of puppies.
Grunion Ajax submits a Grunion Contact Form using Ajax. It makes it super fast for visitors to submit a form.
The Grunion Ajax Javascript file is only loaded if the post or page in question includes the Grunion [contact-form] shortcode, so it’s efficient too.
The only caveat, Ajax submission has not been tested for Grunion Forms included in a widget.
