What process is followed to create custom pages in Mendix?

Creating custom pages in Mendix primarily involves adding new pages and configuring UI elements using the Mendix Modeler. This process allows developers to design user interfaces tailored to specific application requirements while utilizing the drag-and-drop functionality of the Modeler.

When a developer adds a new page, they can choose from various layouts and templates that best fit the application's needs. The Modeler provides tools to customize these pages by adding buttons, forms, images, and other types of UI elements. This fully integrated environment ensures that any changes made are seamlessly incorporated into the app without needing to toggle between different external tools or environments.

The other methods mentioned do not align with the standard Mendix approach. For instance, merely editing pre-existing templates limits the ability to create unique pages tailored to specific functionalities or user experiences. Using an external coding environment defeats the purpose of Mendix's no-code/low-code philosophy, which emphasizes ease and accessibility through its built-in tools. Lastly, running scripts to generate pages automatically does not provide the nuanced control and design flexibility that the Modeler offers, thus not adhering to the Mendix model of custom page creation.
