This is a step-by-step manual to configure a Limesurvey poll to show X questions from a (random) selection of Y question groups.

The proof of concept can be accessed here: https://survey.toolsforresearch.com/index.php/345678. The compliation was borrowed from Tony Partner:
https://www.limesurvey.org/forum/can-i-do-this-with-limesurvey/107889-randomly-select-question-groups#145950

The full manual can be found here: https://toolsforresearch.com/limesurvey-randomly-show-x-out-of-y-question-groups and an excerpt of it is copied below.

1) The slider to choose the number of groups (variable x)

Create a ‘Multiple numerical input’ question with Qcode ‘gcount’. The maximum should match the number of random groups within randomization group (‘y’).

Add a subquestion ‘1’. The variable ‘x’ will be stored in ‘gcount_1’.

2) Random groups

Create the random groups: ‘randGroups1’ in randomization group.

3) Equation in each random group

Every random group should start with a hidden question of the equation type.

The value of the equation is the sum of the RelevanceStatuses for all the other groups in the same Randomization group.

4) Questions within a random question group

The trick is that every (visible) question within each random group must have a relevance equation that checks if the equation of the current random group is less than gcount_1 (the ‘x’ variable). The relevance equation is entered in the general options of each question.
