How to remove paragraph tag in WordPress post content?

To remove the <p> paragraph tag on your post content, just put this code on your child theme function.php file. Just change the “posttypeslug” of the post type slug that you want to remove the paragraph tag.

function remove_wpautop( $content ) {
'posttypeslug' === get_post_type() && remove_filter( 'the_content', 'wpautop' );
return $content;
}
add_filter( 'the_content', 'remove_wpautop', 0 );
