'embed' Easyform with ReCaptcha

I have been 'embedding' Easyforms with pat-inject to reuse form on several pages (works well).

If I (=my customer) wants to add ReCaptcha: Is there a way to do this?

I have only managed to do it by using iframe (which is something I try to avoid).

PS: It looks like it could be possible to insert the Captcha by using:

  <tal:block tal:replace="structure context/@@recaptcha/image_tag" />

But it will 'render outside the form'


Any suggestion welcome
