The HTML aria-required attribute
The aria-required="true" attribute tells assistive technology that a field must be completed before a form is submitted. Prefer the native required attribute on form controls; use aria-required on custom widgets.
Overview
The aria-required attribute indicates that user input is required on a widget before submission.
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-required 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
<div role="textbox" aria-required="true"> … </div>
Values
| Value |

| true | false |
Example
<label for="name">Name</label>
<input id="name" aria-required="true">
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.
