tutorial #6: Autocomplete

Virtually every online form has an Autocomplete feature to simplify and enhance the user interface experience. As an example, we will use a form with name and city inputs. The city form field will automatically fill in major cities as you type in the information.

In this demonstration, you will learn how to build a form with Autocomplete, how to build the jQuery code needed and learn the purpose of each line of code. Also, you will learn how to create and use an Autocomplete form in HTML and CSS.
