Change from using 'this' pointer to using unique IDs for group toggling: - Generate unique IDs for each group (group-0, group-1, etc.) - Pass group ID to toggleGroup() function instead of DOM element - Use getElementById() and previousElementSibling to find elements - Add error handling with console.error for missing elements - Add console.log statements for debugging This approach is more reliable than relying on inline onclick handlers with 'this' keyword, especially when the HTML is dynamically generated.
