### GridField Customization
To alter how the results are displayed (via `[api:GridField]`), you can also overload the `getEditForm()` method. For example, to add a new component.
:::php
class MyAdmin extends ModelAdmin {
private static $managed_models = array('Product','Category');
// ...
public function getEditForm($id = null, $fields = null) {
$form = parent::getEditForm($id, $fields);
$gridField = $form->Fields()->fieldByName($this->sanitiseClassName($this->modelClass));
// $gridFieldName is generated from the ModelClass, eg if the Class 'Product'
// is managed by this ModelAdmin, the GridField for it will also be named 'Product'
$gridFieldName = $this->sanitiseClassName($this->modelClass);
$gridField = $form->Fields()->fieldByName($gridFieldName);
$gridField->getConfig()->addComponent(new GridFieldFilterHeader());
return $form;
}
}
The above example will add the component to all `GridField`s (of all managed models). Alternatively we can also add it to only one specific `GridField`:
:::php
class MyAdmin extends ModelAdmin {
private static $managed_models = array('Product','Category');
// ...
public function getEditForm($id = null, $fields = null) {
$form = parent::getEditForm($id, $fields);
$gridFieldName = 'Product';
$gridField = $form->Fields()->fieldByName($gridFieldName);
if ($gridField) {
$gridField->getConfig()->addComponent(new GridFieldFilterHeader());
}
return $form;
}
}
