Creating custom menu

For custom menu we will have to create the function
For it first of all we will have to declare or register the custom menu in the function.php
There are steps to create custom menu in wordpress

1. creating the function for register the menu
that function will be created in function.php
that is in theme directory

and will write function such as
first of all we will initialize function as below

add_action( 'init', 'joyrelish_menus' );
      function joyrelish_menus() {
         register_nav_menus(
            array(
      'primary-menu' => __( 'Primary Menu' ),
      'secondary-menu' => __( 'Secondary Menu' )
                    )
             );
      }


Now for it you can see the secondary menu in WordPress through wp-admin
go to appearance->menu

Through selected the secondary menu 

create the new menu 

select he page post or something else for he menu
