When a layout is based on another layout, what is the term for the parent layout?

In Mendix, when a layout is based on another layout, the term used to refer to the parent layout is the "Master layout." This concept is key in understanding the hierarchical structure of layouts within the Mendix platform. The Master layout serves as a template that can define common components or styles that can be reused across multiple child layouts, ensuring consistency in design and functionality throughout the application.

The use of a Master layout allows developers to maintain a clean and organized structure, making it easier to implement changes across multiple pages. For instance, if a common header or footer is defined in the Master layout, any modifications made to it will automatically reflect across all child layouts that utilize this Master layout. This enhances maintainability and reduces redundancy in the application's design.

The other terms, while they may describe various aspects of layouts, do not accurately represent the concept of a parent layout that serves as a template for others. By understanding the significance of the Master layout, developers can better manage the layouts in their Mendix applications and create a cohesive user experience.
