The HTML aria-autocomplete attribute
The aria-autocomplete attribute describes how a textbox or combobox predicts input. Values: none, inline (completes in the field), list (shows a list of suggestions), or both. It is for custom widgets, not the native autocomplete attribute.
Overview
The aria-autocomplete attribute indicates what kind of autocomplete a text input or combobox provides.
It is a widget state — a condition that can change as the user interacts. Because ARIA does nothing on its own, you must update this value in JavaScript every time the underlying state changes; a stale state is worse than none. And wherever a native element already expresses the same thing (a checkbox's checked state, the disabled attribute, a <details>'s open state), use that instead.
Like all ARIA, aria-autocomplete changes only the accessibility tree — what assistive technology perceives — never the element's behavior or appearance. The first rule of ARIA applies: if a native HTML element or attribute conveys this, use that instead, and only reach for ARIA when nothing native fits.
Syntax
<input role="combobox" aria-autocomplete="list" aria-expanded="false">Values
| Value |
|---|
| none | inline | list | both |
Example
<input role="combobox" aria-autocomplete="both" aria-expanded="false" aria-controls="opts">Best practices
- Follow the first rule of ARIA — use a native HTML element or attribute that conveys this where one exists, rather than adding ARIA.
- Update the value in JavaScript whenever the state changes — keep it in sync with reality.
- Use the matching native state where one exists (a checkbox's
checked, thedisabledattribute, a <details>'s open state) instead of the ARIA version. - Set it only on an element whose role actually supports this state.
