Interview question for model driven application, how to show and hide fields conditionally?

In this video, you'll learn how to tackle one of the common interview questions for model-driven applications, which is how to show or hide fields based on certain conditions. The answer to this question lies in leveraging the powerful built-in features of the Power Platform, such as business rules and JavaScript.

Business rules enable you to create simple statements that determine how data is displayed on a form. By using them, you can show or hide fields based on specified conditions. For example, you can set a rule to hide a contact field when a lead field is populated.

JavaScript, on the other hand, is a more advanced technique that enables you to perform complex customizations on forms. By writing scripts, you can create highly customized behaviors, validate data, and manipulate the user interface. JavaScript can also be used to show or hide fields conditionally. However, it requires a deeper understanding of coding principles and syntax than business rules.

Overall, there are multiple ways to show or hide fields conditionally in model-driven applications, but leveraging built-in features like business rules and JavaScript can help simplify the process and ensure consistency across your application.

So, if you're preparing for an interview in model-driven application development, make sure to familiarize yourself with these techniques to demonstrate your proficiency and problem-solving skills.
