check current_theme_supports in admin_menu hook

I’m adding a menu and sub-menus via the admin_menu hook in my functions.php. One of the sub-menus I want to add is menus.

I want to make sure that the theme supports menus before I do that, so I tried using the current_theme_supports function, but it returns false, apparently because $_wp_theme_features is still null at this stage.

What should I do? Do you think I really need this check, if I’m anyway in my functions.php? And if I do – should I use a later hook to create my menus? Or any other solution?

Not really sure what you’re asking here, but this allows theme support for navigation menus in your theme.

Place this block of code in your theme’s functions.php file.

if(function_exists('register_nav_menus')){
    register_nav_menus(
        array(
            'header_navigation' => 'Header Navigation',
            'main_navigation' => 'Main Navigation',
            'footer_navigation' => 'Footer Navigation'
        )
    );
}
