EasySocial Custom Fields are build to enhance the productivity, interactivity and user experience of EasySocial. Core and necessary custom fields are pre-installed on your site upon installing EasySocial and you may find them from Components > EasySocial > Applications > Custom Fields. Additional custom fields are available on Application Store on your site and also on our Stackideas Apps Store.
Installing new custom fields are pretty similar to installing new applications. Please read through Applications Documentation for more information.
