Ajax Form extension for Contao Open Source CMS
Allows you to submit your forms that were generated with the built-in form generator via Ajax. After the installation you will have a new content element called "Form with Ajax" available. Simply choose that and enjoy the magic.
It also works with redirects so you can use it in combination with e.g. "mp_forms".
This extension does not require jQuery or MooTools and thus only works in modern browsers.
