We added visibility conditions to subviews so you can specify which moments a subview must appear or not. You could already use business roles to show the right subview (related data of the source object) to the right users. With this new feature you can navigate your end users even more.
Use visibility conditions to subviews to specify under which conditions a subview is shown or not
Visibility conditions are created at the bottom of the edit subview form. Go in builder mode and select the gear icon on the right of a subview. You can define conditions rows based on the current user in the application, the source object where the subview is related to, or you can use an expression.
