There are many cases where you have two different Answer/Topics lists in two different questions, where one list relies on the other and the responses given in one question will determine the Answers/Topics displayed on the other. One example is Car brands and Car models. Selecting specific brands in one question will determine which models will be displayed on the second.

A good way to perform such filters is using an external data list that will hold both lists and the filtering code will be based on its content.

The attached sample will show you an example of this filtering need.

In order to test the sample, you’ll need to perform the following:

• Import the attached .srv file.
• Create the additional data list from the attached Excel file.
• Add the additional data list to the sample survey:
  • By default, the survey is not imported with the subject store assigned to it.
  • Go to the survey’s Advanced tab -> Edit Subject Store.
  • Mark the subject store you see as “deleted” and click on “Remove”. 
  • Add the new data list you’ve created with the “New from common” button.
