How To Edit Top Menu Bar

This is the so-called admin bar. Plugins that you use add their options here so that you can access them quickly. There are 2 ways to edit these:

• Through plugins that can change the admin bar. You can do this with these, for example: https://wordpress.org/plugins/admin-bar/ or https://wordpress.org/plugins/adminimize/
• With individual programming you can also influence the admin bar. You can do this with this hook here: https://developer.wordpress.org/reference/hooks/admin_bar_menu/
