What is a characteristic feature of expression-based filters?

Expression-based filters are characterized by their ability to generate dynamic choice lists based on underlying data. This means that rather than relying solely on a predefined static list, expression-based filters query current data at runtime, allowing for a responsive and adaptable user experience. This feature is particularly useful in scenarios where the available options need to reflect real-time data changes, such as showing active users or updating product lists based on inventory.

The other characteristics mentioned in the options highlight limitations or features that are not applicable to expression-based filters. For instance, while static list options are common in filtering methods, they do not represent the dynamic nature of expression-based filters. Additionally, these filters do not have to consist of multiple choice options nor are they restricted from including user-defined options; rather, they provide flexibility in how options are presented, based on the data source being utilized. Thus, the essence of expression-based filters lies in their capability to provide dynamic responses to user inputs and data states.
