Let's suppose you ask for age and then what to drink. People under 18 should see water and juice, adults should see water, juice and beer. For multiple choice question ("checkbox") this is easy, just use condition for a subquestion. For single choise question ("radiobutton") it's not simple as there is no condition for answer options.

It is of course possible to copy a question, modify copy and use conditions age >= 18 and age < 18. This has of course drawbacks: If you modify text from juice to apple juice you must do the change in two plave. Is there any reasonable other way to this?

We are using 5.x, no older than 5 week ago released version.

Joffm has provided many examples of this.

Insert a hidden (via CSS) multiple-choice question and set its sub-questions with a hidden equation question. You can then filter the list-radio question by the hidden question.

We really need answer option relevance in addition to subquestion relevance.

Any link to an example? I already tried to google this.

Shows how to use the hidden multiple question and how to preset it.

It should also be noted that you don't necessarily need to filter all answers. So, to use your example, you could have a single sub-question with the same code as "Beer" in the hidden multiple-choice.

I made a help page for this: survey.tuni.fi/help/condition-option.html

Nice, but as I suggested above, if these answers are to always be show, you don't need the "wa" or "ju" sub-questions in the hidden question. You can have a "partial" array filter.

I didn't get that to work. ...and now, with another try, it works like a charm.

Gonna change the text later, i guess. Thanks.
