add_menu_page() with different name for first submenu item

Question

The add_menu_page documentation says to pass the menu title as the second parameter:

add_menu_page('Page Title', 'Menu Title', ...);

When adding more pages later via add_submenu_page, the main page becomes the first entry in the submenu:

---

However, I want the first item in the list to have a different name (but still point to the same page), the way Wordpress itself does it:

---

How could I accomplish that in my plugin?

Answer 1

You can make the 'slug' for the submenu page equal that of the top level page, and they'll point to the same place:

add_action('admin_menu', 'my_menu_pages');
function my_menu_pages(){
    add_menu_page('My Page Title', 'My Menu Title', 'manage_options', 'my-menu', 'my_menu_output' );
    add_submenu_page('my-menu', 'Submenu Page Title', 'Whatever You Want', 'manage_options', 'my-menu' );
    add_submenu_page('my-menu', 'Submenu Page Title2', 'Whatever You Want2', 'manage_options', 'my-menu2' );
}

E.g.

Answer 2

Simply add this:

$submenu['my-menu'][0][0] = 'My New Menu Title';

For debugging purposes, you can do a print_r($menu) to check the whole WP menu.

Answer 3

add_submenu_page(
        'tut_theme_settings',       // parent slug
        'Front Page Elements 2',    // page title
        'Front Page 2',             // menu title
        'manage_options',           // capability
        'tut_theme_settings2',      // slug
        'theme_front_page_settings' // callback
    ); 

if different name of first sub-menu create same slug of parent and first child and call same function
