True or False: Web blocks can have output parameters.

Web blocks in OutSystems typically do not have output parameters. They are designed primarily to encapsulate reusable UI components and can accept input parameters, which allow developers to pass data into the web block that can be used internally. However, the nature of web blocks means that they do not return data to the parent screen; they are not structured to send output back.

The notion of having output parameters suggests a two-way data flow, which contradicts the intended usage of web blocks. Input parameters are meant to configure the behavior and appearance of the web block, while the expected workflow is that any data interactions are handled within the current context of the screen or logic. This is why having output parameters is not a feature of web blocks in OutSystems.
