What is the purpose of the Before User Submit trigger?

The Before User Submit trigger is designed to execute logic prior to a record being submitted by the user. Its primary purpose often revolves around manipulating the display characteristics of form fields. This allows developers to dynamically adjust the user interface based on specific conditions before the user submits the form. For instance, it can change the visibility or default values of certain fields based on the context or previous user inputs, enhancing the user experience.

While other triggers and mechanisms are in place for validation and error notification or handling user permissions, the Before User Submit trigger particularly stands out for its functionality in altering how fields are presented to the user just before submission, ensuring that the information is relevant and appropriately configured based on the scenario. This capability is vital to optimizing form usability and ensuring that users have a seamless experience when interacting with records.
