Toolset Interactive BUNDLE – WordPress Custom Types and Fields
Toolset WordPress compares favorably with other plugins in that it is great for developers and provides a very convenient interface. There is a PHP API. Non-programmer users can use a simple graphical interface to work. In addition to custom post types, this plugin also handles custom fields very well. You can not only add them to posts and pages, but also to users. You can also specify how different fields will appear in the WordPress admin area. Another useful feature: the ability to set parent / child relationships between different types of posts.
