1. Block for choosing one of the answer options by the user in the form of buttons.

For example, the question: “How do you assess the quality of the services provided”, and the answer options in the form of buttons: “Excellent”, “Satisfactory”, “Unsatisfactory”.

In this case, the user can select only one of the proposed answers, and will not be able to enter his answer.

To add a button in a block, you need to click on the "add button" button, to delete - click on "remove button".

In this case, validation is not needed, so we leave the "validation type" - "no validation".

2. User input of the answer on their own.

In this case, the “Keypad message” block should be used. The validation type remains “no validation”.

If the issue is meant for phone number, e-mail, the numerical values of the image, choose the appropriate type of validation.

Only if the validation is successful, the user will move on to the next question. If the validation fails, the question will be displayed again.
