+But before you build a combined question, please pause for a moment. Printed questionnaires and online questionnaires differ in important points -- the former offer a lot of space in width, the latter allow filtering and any number of pages. If a tabular presentation looks good in the printed version, it is often better to use several questions in the online questionnaire. Under certain circumstances, irrelevant items (e.g. unused offers) can then be hidden immediately in the following sub-questions.
+Please also note that the combined questions often cannot be displayed well on the small displays of mobile devices. Unlike "normal" questions, SoSci Survey cannot dynamically adjust the display here.

 For example, if the items of question one have the IDs 3, 4 and 5 but the position 1, 2 and 4, question two will ask for the items with the position 1, 2 and 4, regardless of their ID.
-It might happen, that the item AB01_03 corresponds to the item AB02_01, because the position of the items were changed. Consider this when evaluating the results. You can avoid confusion if you don't change any item position after duplicating the question. If needed anyways, you can change the item order of the output by using the function ''[[functions-base#question|question()]]''.

 **Hint:** Randomizing the item order is no problem. Be aware, the setting of question one is the only one regarded, while the other questions follow the first so there are no inconsistencies.
