With <a href="https://github.com/pixelgrade/pixfields" rel="nofollow ugc">PixFields</a> you can have a custom fields visual manager.
Note: this plugin does not add any style to the output of custom fields. Its just adding metadata and offers a way to overwrite the html from the theme. 
The theme should style the output of the metadata.

PixFields

PixFields offers you a nice interface to add custom metadata into your favorite post type.

Advanced Custom Post Types is the perfect solution for any WordPress website which needs more content types like other Content Management Systems. No additional plugins required!
