This plugin will work, "as is", out of the box, but assumes some level of CSS and developer customization to adapt to your site's specific needs.

Styles can be overridden via your theme's style.css

Functionality can be overridden via your theme's functions.php

''Examples''

Don't display metabox on "product" post type:

add_filter( 'display_custom_fields', 'bb_no_product_metabox' );

function bb_no_product_metabox( $true, $post ) {
  if ( $post->post_type == 'product' )
    return false;

  return true;

}

Don't display the product_id metakey

add_filter( 'dcf_postmeta', 'bb_no_product_id' );

function bb_no_product_id( $postmeta ) {
  unset( $postmeta['product_id'] );
  return $postmeta;
}

Don't display metabox title

add_filter( 'dcf_heading', '__return_false' );

Display metabox below content (rather than floated to the right)

add_filter( 'dcf_before_content', '__return_false' );
