Usage Examples

Basic Implementation

// Initialize the accordion
const faq = new AccordionFAQ();

// Programmatically open a specific item
faq.openItem(document.querySelector('.faq-item[data-category="general"]'));

// Programmatically search
faq.filterQuestions('shipping');

Custom Configuration

// Extended configuration options
const faq = new AccordionFAQ({
    allowMultiple: true,        // Allow multiple items open
    autoClose: false,          // Don't auto-close other items
    animationDuration: 300,    // Animation duration in ms
    scrollOffset: 100,         // Scroll offset when opening items
    highlightSearch: true      // Highlight search terms
});
