Bree is designed to be easily extensible by allowing field type implementations to be self contained packages. There are two basic types of resources: field types and field sets.
Field types contain the markup and any additional assets necessary to generate a specialized form input. A field type can have a unique implementation for different field sets.
Field sets are a container for a group of field types. Right now the main function of a field set is to provide common assets across its field types.
A field type, in its most basic form, is just a class that extends Packettide\Bree\FieldType and implements the field() function.
A field set must extend Packettide\Bree\FieldSet and define a $name for the class.
Each field package must have a service provider which extends Illuminate\Support\ServiceProvider. The field type and/or field set will be attached in this service provider's boot() method like so:
// Register a new Field Set
Packettide\Bree\FieldSetProvider::register('Packettide\Bree\FieldSets\BasicFieldSet');
// Specify the field set and then an array with a key/value of a name for the field type and the class in your package which fulfills the implementation
Packettide\Bree\FieldSetProvider::attachFields('basic', array('Colorpicker' => 'Packettide\Colorpicker\Colorpicker'));
Please refer to the Colorpicker field package as an example of how to create and register your own field type.
