Adding a sub-menu to a custom post type

I want to know how to add a new submenu for a custom post type in creating a wordpress plugin.
What I have done for now, I’ve created a custom post type called ‘funds’.

add_action( 'init', 'wnm_add_funds' );
function  wnm_add_funds() {
register_post_type('wnm_funds',
    array(
        'labels'        => array(
                                'name'              => __( 'Funds' ),
                                'add_new'           => __( 'Add New Fund' ),
                                'add_new_item'      => __( 'Add New Fund' ),
                                'edit_item'         => __( 'Edit Fund' )),
        'public'        => true,
        'has_archive'   => true,
        'menu_position' => 100
    )
);

}

This code adds a custom post type called ‘Funds’ and under it is two submenus (‘funds’,’add new fund’). What I would like to do is to add new submenu under funds. Example I would like to add ‘Fund Settings’, so under funds there will be (funds,add new fund,fund settings).

how would i do that?

  1. You can do this with:
    http://codex.wordpress.org/Function_Reference/add_submenu_page
    http://codex.wordpress.org/Roles_and_Capabilities
    I don’t know if the capability is set right for your cause, but this will work

    <?php
    add_submenu_page(
        'edit.php?post_type=wnm_funds',
        'Fund Settings', /*page title*/
        'Settings', /*menu title*/
        'manage_options', /*roles and capabiliyt needed*/
        'wnm_fund_set',
        'CALLBACK_FUNCTION_NAME' /*replace with your own function*/
    );
    

    To add settings/options to the page I recommend the settings API
