An autocomplete dropdown allows the user to search and select one option from a set of choices. When the user enters text into the input field, a list of suggestions are provided.
Searching and results can be auto-populated.
Filtering list items.
Providing only two options. Instead, use Radio Buttons or a Switch.
Basic Autocomplete: Typical “search-as-you-type” function that matches what a person is typing, usually the beginning of a word, or a prefix, part of a word or with a word list.
Instant Results: Sometimes users may prefer to autocomplete actual search results instead of retooling their search phrase. For example, the display of rich information right in the autocomplete instead of a list of suggestions that lead to a search results page.
Whenever possible use the autocomplete ARIA attribute to help users (especially users with cognitive disabilities) fill out the form: aria-autocomplete=true (see additional resources for Legacy ARIA 1.0 Combobox with Both List and Inline Autocomplete and Editable Combobox with Both List and Inline Autocomplete.
On required fields, use the required attribute. It causes screen readers to announce “required” and also triggers the browser to warn the user with a visual tooltip if the user leaves the field blank. Screen readers also announce the tooltip content, when it appears.
When performing form validation, apply the aria-invalid=true attribute to a form control. It will cause screen readers to announce “invalid” when that control gets in focus.
