How to set when the navbar will open the button

Good afternoon guys! I have a menu that, when the administrator is logged in, opens several links, but when the default user opens only a few. The problem is that the system is used on a mobile device as well, hence my question: How can I define when my navbar will turn a button (burger)? Type that when you are a normal user, you can show the menu normally, but when you are an administrator, just enjoy a button (hamburger) and when you click it, open the options.
