How do I leave out an Item in 50% of the questionnaires?

Question

Hi SoSci Survey Online Support,

I would like to leave an Item in a Multiple Choice Question out of the questionnaire in 50% of the cases. How do I do this? (I want to conduct a list experiment).

I thank you in advance for your help!

You can specify the items to be displayed, if you show a question using question() instead of dragging it into the questionnaire.

This, then, can be combined with traditional randomization.
