In this Shoott.com photographer application Typeform, item 3a is a dropdown menu with a question that asks “What is the brand of your camera?”. The sentence in 3b recalls the dropdown options list item selected from 3a. Easy enough. But how does the dropdown option list item chosen for 3b seem to dynamically load options based on the list item options in 3a? For example: in 3a, if the user chooses “Sony.” 3b will state “Sony camera model?” and the dropdown options will be the corresponding Sony option list items. How are they accomplishing this? I’m trying to recreate this for my Tyepform. Please help if possible. Thanks!
