Questions, groups & text blocks
Opina offers different types of questions to help you get all the information you need and text blocks to help you contextualize them. Opina also offers groups to organize the survey and facilitate the respondent's readability.
You can define restrictions for each question to ensure the integrity of the collected information. All the questions can be defined as "required" and, depending on the question type, you can define some additional restrictions (minimum values, intervals, etc).
