@AmiraF34 To modify the mobile view of a Pega Questionnaire, you can create custom CSS styles or modify the existing styles to achieve the desired appearance. You can apply these styles to the questionnaire elements, such as radio buttons and their labels, to display numbers alongside the radio buttons or in any other desired manner.

However, please note that some features may not be supported in certain Pega Platform versions or applications based on Constellation, as mentioned in the context.

As a Support Center moderator, I reviewed the answer and references for accuracy
