A text response matrix is simply a matrix question that allows the survey creator to ask a question about a number of different variables that require a text response. For example, you may want to ask someone to type in all of their contact info (including Name, Lastname, Phone#, Email, etc…). A text response matrix would be ideal for this.
How to Use:
In order to use a Text Response Matrix Question, simply drag it from the list of questions (on the left side of your survey editor screen) and drop it onto the right side of your survey editor (where you see a live preview of the questions).
Once the question has been added, you can view the question options on the left side.
