What does the suggestFunction in an array picker return?

The suggestFunction in an array picker is designed to return a data subset. This subset is derived from the larger dataset based on the user's input or selected criteria. The purpose of this function is to provide a more focused list of options to the user, facilitating a better selection process by filtering out irrelevant items.

When using suggestFunction, it typically examines the current state of the data and the user's input to intelligently suggest items that match. This can enhance user experience by making it easier to choose from a streamlined list tailored to their needs.

This functionality is particularly useful in scenarios where the dataset is large, enabling users to retrieve specific information quickly instead of sifting through the entire dataset. This is the fundamental reason the answer is a data subset rather than a single numeric value, an entire data type, or a blank array. Each of those other choices does not align with the purpose and output of the suggestFunction in the context of an array picker.
