Appear question based on previous question selection


Can someone please help me write a code for the following scenario?

There are 2 questions in one page (Q40 and Q41). Q41 has to only appear if any options are selected in Q40. Q40 is a multi select question.

Also where do I insert this code?

Thank you!

If you look to the Question Library on the Sawtooth Software website, you will find a Branching feature.

This enables you to have multiple questions on the same page, and only display the 2nd question based on a particular response in the 1st question.

You will need to download the ZIP file and import it in to your very own question library.

Follow the step-by-step instructions in the question footer.

Once you've added Branching and the Better Lighthouse Library to your questionnaire, I believe the Branching settings should look like this:

    branchings: [
            dependentQuestion: 'Q41',
            condition: function() {
                var selectQ = 'Q40';
                var items = $('input[name="hid_list_' + selectQ + '"]').val().split(',');
                for (var i = 0; i < items.length; i++) {
                    if (SSI_GetValue(selectQ + '_' + items[i])) {
                        return true;
                return false;
            requireResponse: true
