I have a survey that has a list of values that need to be filtered by the previous question so if question 1=A, Question 2 list is filtered to choices a,b,c. If Question 1=B Question 2 choices is filtered to x,y,z. I also want to allow "other" to show up no matter what the response to Question 1 is. I've used "or_other" but the choice_filter doesn't seem to work. How can I specify other in the choices tab and still use the choice_filter?
