/**
|
|
* Encapsulates a collection of components following the
|
|
* {@link GridFieldComponent} interface. While the {@link GridField} itself
|
|
* has some configuration in the form of setters, most of the details are
|
|
* dealt with through components.
|
|
*
|
|
* For example, you would add a {@link GridFieldPaginator} component to enable
|
|
* pagination on the listed records, and configure it through
|
|
* {@link GridFieldPaginator->setItemsPerPage()}.
|
|
*
|
|
* In order to reduce the amount of custom code required, the framework
|
|
* provides some default configurations for common use cases:
|
|
*
|
|
* - {@link GridFieldConfig_Base} (added by default to GridField)
|
|
* - {@link GridFieldConfig_RecordEditor}
|
|
* - {@link GridFieldConfig_RelationEditor}
|
|

* @subpackage fields-gridfield
