Custom Option Types

You can add custom option types by filtering the option types array:

    $types['custom_type'] = array(
        'label' => 'Custom Type',
        'description' => 'A custom option type',
        'multiple' => false,
        'has_price' => true,
        'has_image' => false,
        'has_color' => false
    );
    return $types;
});

Custom Styling

Override the default styles by adding CSS to your theme:

.wcl-product-options {
    /* Your custom styles */
}

Performance

• Efficient database queries with proper indexing
• AJAX-powered conditional logic for smooth user experience

Troubleshooting

Common Issues

1. Options not showing - Check that the option set is assigned to the product
