Can custom fields be added without a meta box?

Question

I'm building a custom post type entry screen (in code). I would like to have my fields display without a meta box surrounding them, so that they look more like the user profile page. Is that possible, without using a third-party plugin?

Is add_meta_box() the only way to display fields on an admin area post entry/edit screen?

Answer 1

Add this code in functions.php

add_action('admin_init', 'wpse_87339_admin_init');
function wpse_87339_admin_init() {
    wp_enqueue_script('wpse_87339_admin', get_stylesheet_directory_uri() . '/js/admin.js', array('jquery'));
}

and create new js file name admin.js and then add the below code in it

jQuery(document).ready(function($) {
    // Remove all .postbox classes from sidebar
    $('#side-sortables .postbox').removeClass('postbox');

    // Remove .postbox from specific metabox (page attributes)
    $('#pageparentdiv').removeClass('postbox');
});
