Thanks for your patient. I've just updated the plugin with filters for the post fields. I also added a template loader, which you can use to define the template for each field (similar to what WooCommerce do).
I was thinking about this and the "require" attribute. Haven't found a good way to implement them in the shortcode. What do you think about this? Any suggestion?
Thanks for your comment. I didn’t think about this, just thougth $this is enough. I’ve just released new version 1.0.2 with these properties public. Please update.
Your code looks fine. I just found the problem. It's just the MB Settings Page is loaded at init with priority 5, which is later than widgets_init (fires at init with priority 0). So, to solve this problem, simply replace widgets_init with init!
Hi, the code still requires the Meta Box plugin to use. It's the heart of all extensions. With the exported code, you can remove the MB Builder extension, but still need to keep Meta Box active!
