customize_loaded_components filter

This allows Core components to be excluded from being instantiated by filtering them out of the array. Note that this filter generally runs during the ‘plugins_loaded’ action, so it cannot be added in a theme.

To use customize_loaded_components filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_customize_loaded_components_defaults which takes 2 parameters and we registered using add_filter. The first parameter customize_loaded_components is name of the hook, The second parameter modify_customize_loaded_components_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove customize_loaded_components filter.


    Below are the 2 parameters are required to use this hook.

  • $components : (string[]) Array of core components to load.
  • $manager : (WP_Customize_Manager) WP_Customize_Manager instance.

Live Example

 * Removes the core 'Menus' panel from the Customizer.
 * @param array $components Core Customizer components list.
 * @return array (Maybe) modified components list.
function wpdocs_remove_nav_menus_panel( $components ) {
    $i = array_search( 'nav_menus', $components );
    if ( false !== $i ) {
        unset( $components[ $i ] );

Below is an example how you can use this hook.

                        function modify_customize_loaded_components_defaults($components, $manager) { 
                            // Update the $components variable according to your website requirements and return this variable. You can modify the $components variable conditionally too if you want.

                            return $components; 
                        // add the filter
                        add_filter( "customize_loaded_components", "modify_customize_loaded_components_defaults", 10, 2 );

To remove a hook callback, use the example below.

remove_filter( "customize_loaded_components", "modify_customize_loaded_components_defaults", 10, 2 );

Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
