What are the default options for popups in Mendix?

In Mendix, the default option for popups is designed to be resizable with their size determined automatically, utilizing a layout grid as the outer layer. This approach ensures that the popup can adapt to various screen sizes and resolutions, providing a responsive user experience. The incorporation of a layout grid allows for better organization of the contents within the popup and helps maintain a consistent design across different devices.

By using a flexible layout, Mendix simplifies the development process, as developers do not have to manually define the exact dimensions for each popup. Instead, the platform manages this dynamically, focusing on content and usability. The ability to automatically determine the popup's size means that it will effectively accommodate the information being displayed without imposing rigid constraints, thus enhancing user interaction.

This design philosophy aligns with modern web application standards, prioritizing both functionality and responsiveness, which are critical for today's diverse range of users and devices.
