How to remove slug metabox from custom post type's page?

Question

I just discovered a new meta field on the newly created custom post type page. The meta name is slug, and it's under the wp editor field. What's that, and how can I remove it?

Answer 1

You can remove the slug metabox from a post type with remove_meta_box:

add_action( 'add_meta_boxes', 'my_add_meta_boxes' );
function my_add_meta_boxes() {
    remove_meta_box( 'slugdiv', 'my_post_type', 'normal' );
}

Answer 2

on the top right of the page where you edit your post or page you will see two buttons: [Screen options] and [Help]. Click on [screen options]. You will see all kinds of options, unmark the one labeled "Slug" and it will disappear from the post/page edit page.
