Handling Nested HTML Elements with ARIA Roles in React for Accessibility Issues
I've been struggling with this for a few days now and could really use some help. I'm sure I'm missing something obvious here, but I am currently building an accessible React component that contains nested HTML elements, and I am having difficulty ensuring that the ARIA roles are properly applied without causing unexpected behaviors. I have a structure where I have a main button that expands to show additional content, and I'm using ARIA attributes to manage this interaction. However, when I inspect the output in screen readers, it seems to ignore the nested roles. Here’s a simplified version of my code: ```jsx import React, { useState } from 'react'; const AccessibleComponent = () => { const [isOpen, setIsOpen] = useState(false); const toggleContent = () => { setIsOpen(!isOpen); }; return ( <div> <button aria-expanded={isOpen} aria-controls="additional-content" onClick={toggleContent}> Toggle Content </button> {isOpen && ( <div id="additional-content" role="region" aria-labelledby="toggle-button"> <p>This is additional content that gets revealed.</p> </div> )} </div> ); }; export default AccessibleComponent; ``` When testing in NVDA and JAWS, the screen readers do not seem to announce the additional content correctly after clicking the button. I have tried changing the roles and ensuring that the IDs match up properly, but it still doesn’t seem to work. Additionally, I’ve made sure to include `role="region"` for the additional content, and I have set the `aria-labelledby` attribute to point to the button, which I believe is the correct way to indicate relationships. I am using React 17 and have ensured that my HTML structure is valid. I looked into using `aria-live` regions as well but am unsure if that’s the right approach here. Any advice on best practices for managing nested ARIA roles in React components for accessibility would be greatly appreciated! I'm working on a application that needs to handle this. Any ideas what could be causing this? I'm working on a mobile app that needs to handle this. What am I doing wrong? Am I missing something obvious?
