I'm currently passing an array that looks like this: [ {"category" : "Category 1", "questions": [ "Question 1", "Question 2", "Question 3" ]}, {"category" : "Category 2", "questions": [ "Question 1", "Question 2", "Question 3" ]}, {"category" : "Category 3", "questions": [ "Question 1", "Question 2", "Question 3" ]}, ]
