Meta Box Group

Meta Box Group is an extension of the WordPress Meta Box plugin which allows you to put custom fields in groups to organize, arrange post meta data clearly and logically. These groups of custom fields can be cloned (repeated) and reordered.

How meta box group works
How group works

Organizing custom fields in groups can be useful in situations where:

  • Your data is hierarchical and you want to arrange and store it in a more structured way. This kind of data will be stored by the extension in a multi-dimensional format, making is more efficient at accessing information.
  • Some custom post types require un unknown number of entries and each entry contains some custom fields. For example, a collection can have multiple books, each with the different author, content, publish date, etc. The Meta Box clone feature will store this information with ease.

Multi-level nested groups are supported

Multi-level nested groups are supported (with cloning feature)

Since version 1.1, the Meta Box Group supports multi-level nested groups with no limit for nesting level. The groups, sub-groups, and fields can be cloned as you see in the screenshot above.

This feature allows you to create a better structure for your data and opens an unlimited possibility using the extension to add more data for your posts.

Technically, Meta Box Group extension creates a new field type group, which can contain other fields. Declaring sub-fields of a group is the same as normal fields, so you don’t have to change your code too much to use this extension.

In order to display custom fields of a group better, you can incorporate Meta Box Group with Meta Box Columns to arrange fields horizontally in columns in a grid (see the screenshots below). By default, Meta Box Group displays fields vertically like normal fields.


  • Organizes custom fields in groups for better appearance and data structure
  • Groups are clonable (repeatable)
  • Supports clonable (repeatable) field types. All field types now can be cloned.
  • Supports nested groups since 1.0.7 and multi-level nested groups since 1.1
  • Integrates with existing meta boxes and custom fields easily with a few lines of code

Example of use cases:

  • You have an “album” post type and each album has a list of tracks (unknown number), each track has information: title, single, composer, genre. Then you can create a group for the album, which has 4 sub-fields for title, single, composer, genre. The group is cloneable which allows you to add more tracks.
  • You have an “event” post type which can happen in several days, each day will have different opening times. Then you can create a group (cloneable) for the event, which holds information of the event in a single day. And you need a sub-group to store opening times of the event each day.


Note: If you use multi-level nested groups, then cloning media fields and WYSIWYG fields can be buggy. It works ok without multi-level nested groups.
