CMB2 Field Type: Flexible Content

CMB2 Flexible Field The CMB2 Flexible Field allows the creation of group layouts, which can then be selected and switched between by a user. Each layout group contains a set of existing CMB2 fields, defined in an array in the field setup. These layout groups are then toggleable, sortable and repeatable. The data itself is saved to the field's ID in a serialized and iterable array with the layout group ID attached. Adding a Flexible Field Adding a flexible field is the same as adding any other CMB2 field. The only addition is the layouts option, which should contain an array of arrays, each with a separate group. To begin, set up a standard CMB2 metabox: Getting Data from a Flexible Field Flexible fields are stored in a single meta key, and can be retrieved using the WordPress API. This will return an array of data, each with the layout key defined as layout and the group's data by field ID.
