Yaniv,
The multilang filter now works OK, since Mike's fix. However, since the HTML editor is not available to the "possible answers" field, you have to encode your filtered content "by hand". Here is an example, with English and French.
HTML contents of the Question text (obtained by using the Lang dropdown list in the HTML editor menu):
<span lang="en" class="multilang">What is your favorite drink?</span> <span lang="fr" class="multilang">Quelle est votre boisson préférée ?</span>
Possible answers (to be coded by hand)
<span lang="en" class="multilang">coffee</span><span lang="fr" class="multilang">café</span>
<span lang="en" class="multilang">beer</span><span lang="fr" class="multilang">bière</span>
<span lang="en" class="multilang">milk</span><span lang="fr" class="multilang">lait</span>
Attached shows the view screen with English or French as current language.
Joseph
PS.- There is however a display of both languages on the View all responses page. I will look into this problem now and find a fix.
