Pipe Answers from Dynamic Matrix or Panel

You can populate the choice options of selection-based question types (Single- and Multi-Select Dropdown, Checkboxes, Radio Button Group) with answers copied from other selection-based question types (see the Carry Forward Responses demo). This example demonstrates a more advanced use case, in which choices are dynamically sourced from cell values of Dynamic Matrix and question values in Dynamic Panel.

Each choice item consists of a value saved in survey results and a text displayed in the UI. To construct a choice item, specify the following properties for a choice-based question:

• choicesFromQuestion
  The name of a Dynamic Matrix or Dynamic Panel.

• choiceValuesFromQuestion
  The name of a matrix column or dynamic panel question that supplies choice values to be saved in survey results.

• choiceTextsFromQuestion
  The name of a matrix column or dynamic panel question that supplies choice texts to display in the UI. If this property is undefined, choice values are both used as display texts and saved in survey results.
