Often we want to ask users a question with a large set of predefined answers (e.g. the country where they are in). A multiple-choice question will do the job but will be awkward to use because finding the answer the user chooses may require a lot of scrolling.
In such cases,
*searchable questions are a more user-friendly solution. Here, you still have a list of valid answers that you want your user to choose from, but the user initially sees a box where they can start typing their answer. As they do, a drop-down list appears with matches for what the user is typing:
This is the syntax you would use:
*question: Please enter the country where you live: *searchable Andorra Angola Antigua and Barbuda Argentina Armenia
