Hi everyone,
I want to do a questionnaire with LimeSurvey. First, the user needs to select his own address. Take the United States as an example, the first list should show the names of the 50 states of the United States, and the second list should show all the counties below the states selected by the first list. May I ask how to realize these two related lists?
Thanks.

Unfortunately you forgot to answer the initial questions.
So it is a bit difficult to answer.

But:
Use an array dual scale with drop-down presentation
Here a sample survey with German states.
