To create a user filter with dynamic choices based on your data, what must you do?

To create a user filter with dynamic choices based on your data, developing an expression-based filter is essential. This method involves using Appian expressions to pull data dynamically from your records or other data sources at runtime. Expression-based filters allow developers to create filters that adapt to changing data and user interactions, providing a more personalized and relevant experience for the user.

Dynamic filters can leverage logic to retrieve and display choices that reflect the state of the underlying data, such as new records or updates in existing records. Because it is adaptable, the expression-based filter can cater to various scenarios and conditions defined by the developer, thereby enhancing the usability of the application.

The other options do not enable the creation of dynamic filters. Selecting a static filter option would only provide a fixed set of choices that do not change based on the data. Allowing multiple selections does not impact the dynamism of the filtering options; rather, it merely alters how many items a user can select from a given set. Creating multiple filter options does not address the need for those options to be dynamic; without being tied to an expression, they could remain static.
