With the current version of Recaptcha (reCAPTCHA API version 2.0), you can have multiple Recaptchas on one page. There is no need to clone the Recaptcha nor try to workaround the problem. You just have to put multiple <div> elements for the Recaptchas and render the Recaptchas inside them explicitly. This is easy with the … Read more
