Released: April 30, 2025

SurveyJS v2.0.7 introduces a new Loop and Merge functionality and includes big fixes and minor enhancements.

Loop and Merge is a feature that allows you to repeat a group of questions and combine the responses into one data object. The loop can either iterate over the same set of questions for each item or adjust dynamically based on user input. For instance, you can create a survey in which respondents are asked to select from a list of products and then answer a set of repeated questions for each selected product.

Respondents can exit a loop when they want to, or the loop can break automatically when a certain condition is met. This may happen when a maximum number of entries is reached, a specific value is entered, or a validation rule is triggered. Once the loop ends, the respondent can proceed to the next question or submit the survey.

The Loop and Merge feature also supports nested loops. In a nested loop setup, an outer loop iterates over a primary list of items, while an inner loop handles a related set of sub-items. For example, a form might ask an organization owner to provide information about departments (outer loop) and the employees within each department (inner loop).
