Polls in 1C-Bitrix: is it possible to make a “conditional question” (branching / interruption), after which the survey will end or “jump”?

Question

CMS

I figured out how to create and add a poll to the page through the admin panel. You need to create a question so that on a certain answer of which the poll will be interrupted and a message like "Survey completed! Thank you for participating in our survey" is displayed.

a.delete_at(9) # Возвращает nil {вне диапазона).

Answer 3

You just check each element of the array with a for loop and a method to check accordingly, if the element is a string, then delete
