1. Open the survey builder. On the left tab under the Questions you can see all the questions and question groups of the survey.

2. You can move them by holding and dragging the question or question groups to the wanted location

Notice that you can move questions from different question groups by dragging & dropping the question to the desired question group. In the same way, you can move a question from a question group to be as an individual question without a group.
