You’ve not explained what changes you want to make to the admin bar, so you need to share more details before we can try to help 
i want to remove the multi level drop down and just keep it to single level. also remove the wordpress search and put in the buddypress search.
for CSS – I want to change the weight and background of the admin bar.
also add more menu items of my own.
The WordPress Admin Bar (not BuddyBar) is a different bar entirely.
Try finding something on the WordPress forums:
https://wordpress.org/support
Can also try this plugin:
https://wordpress.org/extend/plugins/wp-custom-admin-bar/ (haven’t tested it myself)
i want to edit the bp-menu within the admin bar.
When I used buddybar, i did it like this
function my_alter_bp_adminbar(){
remove_action(‘bp_adminbar_menus’, ‘bp_adminbar_account_menu’, 4);
add_action(‘bp_adminbar_menus’, ‘my_adminbar_account_menu’, 50);
}
add_action(‘wp_footer’,’my_alter_bp_adminbar’,1);
How can I do the same with wp-admin bar.
thanks
