How to fix aria required attr on Shopify Plus
Add all required ARIA attributes (such as aria-expanded and aria-controls) to every interactive element that uses an ARIA role, so assistive technologies can communicate widget state to users.
Steps for Shopify Plus
- Same as Shopify above; Shopify Plus also allows customisation via the Checkout editor — for checkout-page widgets, go to Settings → Checkout → Customize and inspect the checkout liquid files in your theme code editor.
- For headless Shopify Plus storefronts (Hydrogen/custom), locate the React/Vue component responsible for the interactive widget and add the ARIA attributes as props, then wire the state variable to aria-expanded.
What is aria required attr?
ARIA (Accessible Rich Internet Applications) roles tell screen readers and other assistive technologies what kind of widget an element is — for example, a button that opens a dropdown, a tab panel, or an accordion. Each ARIA role has a defined set of required attributes that must also be present for the widget to make sense. For instance, a button that expands a menu must include `aria-expanded` (so the screen reader can announce "expanded" or "collapsed") and typically `aria-controls` (so it points to the element it controls). When those required attributes are missing, the role declaration is incomplete and the assistive technology cannot convey the correct state or relationship to the user.
Screen reader users — who often navigate by keyboard only — rely entirely on ARIA state attributes to know whether a menu is open, a tab is selected, or an accordion panel is visible. Without `aria-expanded`, a screen reader user has no way to know whether a dropdown they just activated is open or closed. Without `aria-controls`, they may not find the content that just appeared. This directly breaks the shopping experience for blind and low-vision customers. WCAG 2.x Success Criterion 4.1.2 (Name, Role, Value) is a Level AA requirement, meaning it is referenced in most accessibility laws worldwide (ADA, Section 508, EN 301 549, AODA). Failing it exposes your store to legal complaints and demand letters. It also signals to Google's quality systems that the site has usability issues, which can indirectly affect organic rankings.
