What is a best practice for configuring choices in Screen Components?

Using a choice resource only when the other options are not available is a best practice because it promotes efficiency and maintainability within a Salesforce application. When designing Screen Components, it's important to strive for configurations that minimize complexity and maximize usability for both developers and end-users.

Choice resources can be beneficial but may lead to unnecessary complication if overused. By utilizing other methods, such as picklists or choice sets, developers can leverage built-in functionalities that are easier to manage and modify over time. This approach not only simplifies the overall design but also often enhances performance, as less custom configuration means less room for errors and easier updates.

By reserving choice resources for situations where no other viable options exist, developers ensure that they maintain a balance between flexibility and simplicity. This use case-centric approach makes it easier to manage changes in the future, as it allows for the use of standardized options without creating an excess of custom solutions that could lead to higher maintenance costs or user confusion.
