Expression Manager also supports group-level relevance. This makes it easier to implement looping. Say you want to collect information from up to 10 entities (such as products or people from a household), where you first determine how many entities need follow-up (such as by asking how many people live in a household or having people check which products they like from a long list). After knowing how many entities need follow-up, you can use Group-level relevance like {count >= 1}, {count >=2}, ... {count >= 10} for each of the 10 groups of follow-up questions. Within each group, you can have question-level conditional logic (e.g., gender or age-specific follow-up questions for each subject). The question and group-level relevance equations are ANDed together to determine which should be shown.
