Add a single select feature to smart questions
There is a need to provide a new type of questions: smart single select questions. This can be achieved by adding a new type or by adding a checkbox to the original smart questions.
I reopened this ticket by mistake, so I closed it again as 'Ready for Showcase'.
Improvement works properly.
