Type Ahead Block element provides auto complete and search.

• A. Automatic form submission
• B. Data validation only
• C. Scheduling tasks
• D. Auto complete and search with matches shown

Answer: (D)

Type Ahead Block is built to speed up data entry by giving live suggestions as you type. It combines auto-complete and search: as you input characters, it queries the data source and shows a list of matching results for you to pick from. This helps you quickly find and populate a value, especially from large datasets, and keeps input consistent. It isn’t about automatically submitting a form, nor is it limited to data validation, and it isn’t used for scheduling tasks. The essential idea is that you get auto-complete with matches displayed for easy selection.
