What is the primary layout of a study?
Every study requires a primary layout, or validation fails. 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.
If you change the name of the primary layout, the change affects all forms. For example, 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.
