What configuration allows users to filter a database of items in a shopping application?

The selection of an auto-complete control with a data page as the correct configuration for filtering a database in a shopping application is based on the functionality and user experience it provides. An auto-complete control is designed to enhance user inputs by suggesting options based on the user's typing, which allows for a more dynamic and interactive filtering process.

When integrated with a data page, the auto-complete control retrieves options from a defined data source, making it capable of efficiently filtering through a large dataset. This ensures that users can quickly find specific items they are interested in without having to scroll through an exhaustive list, thereby improving the overall usability of the application. The combination of real-time suggestions and data retrieval provides a powerful mechanism for filtering, which is particularly valuable in shopping applications with extensive inventories.

The other options may not offer the same level of efficiency or user experience. For example, a drop-down list with a clipboard page might not dynamically update based on user input, and a drop-down list with a local property might not allow for a comprehensive filtering capability across broader datasets. A clipboard page alone does not provide any interactive filtering mechanism for users.
