The MB Include Exclude extension for Meta Box is a server-side visibility tool that allows developers to control exactly where and for whom meta boxes appear. Unlike Javascript-based toggles (like MB Show Hide), this extension works when the page loads or upon saving, making it ideal for streamlining the backend without the overhead of real-time scripts.
This is EXACTLY the same product as distributed by the developer. Sales Page

You can target meta box visibility using several parameters. Each can be applied as an include (show only if) or exclude (hide if) rule.
Post Details: ID, parent, slug, is_child (boolean).
Templates: template (Page template file names).
Taxonomies: category, tag, or any custom taxonomy (supports IDs, names, or slugs).
User Roles: user_role (Requires MB User Meta for profile screens).
Custom Logic: custom (Accepts a string representing a custom PHP function name for bespoke logic).
In your code, you add an include or exclude key to your meta box configuration array.
No Live Toggling: This extension does not hide/show fields instantly when you change a category or template in the editor. For real-time interactivity, you need MB Show Hide or MB Conditional Logic.
Server-Side: Because it runs on the server, it is highly secure for sensitive data fields that shouldn’t even be rendered in the HTML source if conditions aren’t met.
Modular: It can be used as a standalone extension or as part of the Meta Box AIO bundle.
