trying to replace custom menu

U am using as a CMS and have a navigation menu in the header. This works fine, but I want to replace the custom menu with a drop down menu.

To do this I have installed a widget and registered the new menu in functions.

Admin panel > menu > Theme Locations says “Your theme supports 1 menu” but in fact both menu’s show up in the dropdown menu. So I deleted the registration of the old custom menu in functions.php.

It now reads `add_action( ‘init’, ‘register_my_menu’ );

function register_my_menu() {
register_nav_menu(
‘navbar-menu’, __( ‘navbar’ ) );
}

add_theme_support( ‘menus’ );`

I keep seeing the old menu, have refreshed the page many times. I made sure I saved the menu too.

Can some one help me to either replace the custom menu with a dropdown one or at least have it as a choice?

Thank you.
