|
|
+ Select2 supports a small subset of options in every build that is
|
|
|
+ generated. Each option typically has a decorator that is required that
|
|
|
+ wraps an adapter, adding support for the option. This is only required
|
|
|
+ when a custom adapter is being used, as Select2 will build the required
|
|
|
+ adapters by default.
