I'd like to have a one-page survey where language changes dynamically upon selecting language in a question of the Language switch question type, rather than using the default language changer (which is difficult to incorporate in the survey design). Is this possible? By default, with the Language switch question type, the language only changes after moving to the next page. In my case, however, respondents may want to change languages repeatedly for all questions.
I suppose one way of doing this would be to separate the languages into individual questions, and use Relevance equations to call the appropriate questions upon switching the language, but this would make my survey very unwieldy. Is there a better way?
I'm not sure if I completly understood your question, but I try.
Instead of the language switch question type you could use a question of the type 'text display' or 'equation' and insert in the questiontext:
{LANGUAGECHANGER}
(You can add more text if you want)
With this, the language changes immediatly without moving to the next page.
