Contact Form 7 can provide multilingual forms by default. You don’t need help of extra plugin to do it.
Contact Form in Your Language
Hi Takayuki Miyoshi,
it’s great that we can choose language for a form.
But many users need a translation of same form for different languages (same page, but with many translations).
With your plugin at moment i have to create a copy of same form for different languages.
WPML’s support or a WPML’s addon for CF7 i think that would be a fantastic feature.
Look this post tp see how many user need it: http://wpml.org/documentation/support/translation-for-texts-by-other-plugins-and-themes/how-to-use-contact-form-7-in-multilingual-websites/
Thank again for this awesome plugin!
Regards
