Bootstrap 4 Version
Here is a list of the most notable changes between the Bootstrap 3 version and the Bootstrap 4 version:
- The filename has been changed and prefixed with class- to better fit PHP coding standards naming conventions.
- New Name: class-wp-bootstrap-navwalker.php
- Old Name: wp-bootstrap-navwalker.php
- Icon and link modifier handling is now done through the CSS Classes menu item input instead of the Title input.
- Icon only items are possible using icon classes in combination with the sr-only classname.
