WP Bootstrap Navwalker

This custom nav walker class allows theme developers to output Bootstrap 4 (and 5) navigation markup directly from the WordPress menu manager. It works with standard wp_nav_menu() calls, so no extra configuration is needed beyond including the class.

• Bootstrap 4 & 5 Support: Generates correct HTML and CSS classes for Bootstrap 4.0+ navigation, with a v3 branch available for older versions. Compatible with Bootstrap 5 when using namespaced data attributes.
• Built-in Menu Manager Integration: Works with the WordPress menu admin, allowing users to create and manage navigation menus as usual. The walker automatically applies Bootstrap classes to list items, links, and dropdowns.
• Icon & Link Modifier Support: Add Font Awesome or Glyphicon classes to menu items via the CSS Classes field. Supports icon-only items with the sr-only class, disabled links, dropdown headers, dropdown dividers, and plain dropdown text.
• Easy Implementation: Include the class-wp-bootstrap-navwalker.php file in your theme and pass a new instance to the wp_nav_menu() arguments. Can be set as the default walker for all menus using a filter.
• Customizer Edit Shortcut Fix: Provides a workaround to restore the menu edit shortcut in the Customizer preview by passing the class name string.

The walker is fully compliant with WordPress.org theme review guidelines and requires no modifications for submission. It does not include Bootstrap CSS or JS; those must be added separately.
