Meta Box DEVELOPER BUNDLE – WordPress Custom Fields Framework
This is a powerful, professional and lightweight toolkit for developers, allowing you to create an unlimited number of custom meta-blocks and custom WordPress fields.
The plugin provides a huge selection of fields (over 40) and many options for each type. As a result, the plugin allows you to create a meta-field of almost any complexity.
Meta Box is designed for developers: metaboxes and fields are created programmatically. Therefore, you need basic knowledge in php!
When the basic functionality is not enough, there are extensions. For example, they allow you to create a meta-field not only for posts (by default), but also for users, taxonomy elements, comments, or create separate settings pages. Fields can be repeated and displayed as you like: in the form of columns, tabs or groups.
