What must be configured for a Mendix app to support offline capabilities?

To enable offline capabilities in a Mendix application, it is essential to configure the offline settings and enable offline support. This process involves defining which data entities and pages should be accessible when the app is offline. The configuration allows the application to operate seamlessly without a persistent internet connection, thereby ensuring that users can continue to work and sync their data once they are back online.

In a Mendix application, this includes setting up the necessary entity settings for offline storage, specifying which entities should be cached for offline use, and handling data synchronization effectively. The offline capabilities in Mendix are built to streamline the development process, making it easier for applications to provide functionality under various network conditions.

In contrast, simply requiring online access would contradict the essence of offline capabilities. Manual coding is not necessary due to Mendix's model-driven development approach, which primarily allows developers to configure features through visual tools rather than hand-coding. Lastly, claiming that offline functionality is not possible within Mendix overlooks its robust support for offline capabilities, which is a key feature of the platform.
