We are currently implementing Pega survey along with Pega Marketing for Comms. Both has the version 7.2.1. But it seems like all the Survey related UIs are final rules and its preventing us to do any sort of Customization. However customer provided UI design was quite fancy but survey seems to be very primitive for them. WIll Pega product team will be able to provide any HFix in order to make this happen.

Survey uses question templates to customize the UI. Although you cannot change the structure of layouts, you can apply the styling on these layouts according to your needs. These question templates are available rules. For eg. radio type questions use a template 'SimpleQuestionRadio' which can be overridden in the application ruleset for styling purpose. Please note that you need to re-save your questions after modifying the template to reflect the changes.
