Details
- The
maxgroupstag is intended for use with hidden checkbox (multiselect) variables, coded multiple select variables, and quotas. -
maxgroupscan accept a static value (e.g.,maxgroups: 2), a dynamic value like a question reference (e.g.,maxgroups: $Q2), or a Perl conditional statement. - Quotas are single select variables by default. Apply the
maxgroupstag to make the quota a multiselect variable. - Hidden checkbox variables and coded multiple select variables allow respondents to be assigned to all qualifying options by default. Apply the
maxgroupstag to limit the number of groups they can qualify for. -
Heredoc can be included with
maxgroupsto define more complex logical conditions.
Tip! The maxgroups tag is not intended for visible questions. For respondent-facing questions, use the maxChecked tag instead.
Additional examples
Conditioned 'maxgroups' with 'if else'
Perl "if/else" statements can be used with maxgroups. In QSOME_ACTIVITY, respondents qualify for up to four activities if they rated Yoga (Q1B, row 7) a 4 or higher; otherwise, the limit is three. All assigned activities must also meet the condition decorator criteria.

Heredocs with 'maxgroups'
For more complex conditions, heredoc can be used within the maxgroups tag. QRESTAURANTS uses an "if/elsif/else" statement to define conditions for when to assign each respondent to one, two, or three buckets based on their selection at Q10.
