Block is the element that aggregates survey pages. This functionality will allow you to divide the survey into any number of blocks and then set rotation and logic for each block.
Blocks usage :
Blocks can be used in market research (ad or market concepts testing) or to simplify survey architecture. The order of display different elements that are evaluated can impact the answer choices selection. Randomisation can help to eliminate this issue.
You can select blocks that will not be rotated. This way you can create a section with the statistical information, invitation or descriptive section that will always stay at the same place.
NOTE. If you turn on block rotation, the system will turn off block logic.
The option is available in the Professional and Enterprise plans.
