 An easy to understand example to remove a admin submenu item is :
 remove_submenu_page( 'plugins.php', 'plugin-install.php' );
 remove_submenu_page( 'plugins.php', 'plugin-editor.php' );

 Using the add_action admin init one can remove all submenu pages except:

 Appearance -> Customize, Header and Background.

 I found the following code to remove these sections.

 //Remove the custom options provided by the default twentyeleven theme.
 https://wordpress.org/support/topic/remove-header-and-background-option-
 pages-in-twenty-eleven-child-theme?replies=11
 add_action( 'after_setup_theme','remove_header_background', 100 );
 function remove_header_background() {
         remove_custom_background();
         remove_custom_image_header();
 }

 function remove_customize_page(){
         global $submenu;
         unset($submenu['themes.php'][6]); // remove customize link
 }
 add_action( 'admin_menu', 'remove_customize_page');


 Having to add extra code shows lack of consistency. Removing Customize,
 Header and Background should be just as simple as:
 remove_submenu_page( 'themes.php', 'customize.php' );
 remove_submenu_page( 'themes.php', 'customize-header.php' );
 remove_submenu_page( 'themes.php', 'custom-background.php' );
