The frame is designed to perform the role of page-template, and should therefore be placed directly in the project's tree. In the project-template "Signal groups", for the first signal object, this frame is included in the role of a template that allows you to create on its basis a set of pages of the group of overview. Frames-widgets, for which there are not set the links, will be hidden at runtime and will be performed the proportional scaling to missing full rows and columns to fill the entire frame.
