What is the primary layout and how do I set it?
You set the primary layout for a study at the study level. The first layout that you create for a form or item is given the name of the primary layout.
Note:
Changing the name of the primary layout affects all forms. If a form has a layout named Main, and you choose to use the layout named Spanish as the primary layout, then all layouts named Spanish become the primary layouts.Parent topic: Layouts
