Autocomplete

Definition

Autocomplete, also known as type ahead and predictive text, offers suggested text to complete a word or phrase a user is typing based on words the user has previously typed.

Usage and Specifications

Used appropriately, autocomplete is a handy feature for users. It has the potential to increase completion rates of forms and surveys by eliminating repetitive data entry. Use autocomplete in forms, surveys, and other text entry fields. Because it is possible to enable autocomplete field-by-field, we recommend user testing to confirm which default options will work best for your users.
