Doesn't Work For Bootstrap 5 Theme

@Thomas Kaisuka
Are you using https://www.drupal.org/project/bootstrap5 →

This module doesn't work for my theme, either (Notech, purchased from Themeforest). After a lot of fiddling and no joy, I've uninstalled it. A shame.

The menu attributes also not adding for me in Olivero theme. I am using Drupal 10.2.3.

Yes @ravi Am using that Boostrap 5 theme

Hi @Thomas Kaisuka

This is work for me you may be change bootstrap5 version hare attached screnshot

The module doesn't work with main navigation that ships with Drupal installation and using the bootstrap5 sub-theme, but it does work with custom created menus. Link classes apply for my custom menus, but not for main navigation.

Working alternative https://www.drupal.org/project/link_attributes →

Also the parent ul class gets renamed from .nav to .menu with menus_attribute, but stays .nav with link_attributes (all tested on bootstrap5 sub-theme)

This sounds like the viable option for the Boostrasp 5 subtheme https://www.drupal.org/project/link_attributes → .

Problem solved for me now.
