Requirements

• SilverStripe 4.5+

Installation

• Download the module from here https://github.com/webbuilders-group/silverstripe-gridfielditemtype/archive/master.zip
• Extract the downloaded archive into your site root so that the destination folder is called GridFieldItemType, opening the extracted folder should contain _config.php in the root along with other files/folders
• Run dev/build?flush=all to regenerate the manifest
• Upon entering the cms and using GridFieldItemType components for the first time you make need to add ?flush=all to the end of the address to force the templates to regenerate

Usage

If you are working with one of the pre-configured GridFieldConfigs you must first remove the default GridFieldDetailForm and GridFieldAddNewButton components replacing them with ItemTypeDetailForm and AddNewItemTypeButton respectively

use WebbuildersGroup\GridField\ItemType\AddNewItemTypeButton;
use SilverStripe\Forms\GridField\GridFieldConfig_RecordEditor;

$config = GridFieldConfig_RecordEditor::create(10);
->removeComponentsByType('GridFieldAddNewButton::class)
    ->removeComponentsByType(GridFieldDetailForm::class)
    ->addComponent(new AddNewItemTypeButton($yourOptionsMap, 'buttons-before-left', 'empty string', 'default'))
    ->addComponent(new ItemTypeDetailForm());

If you are using the base GridField config you need to add both the AddNewItemTypeButton and ItemTypeDetailForm to your config

use WebbuildersGroup\GridField\ItemType\AddNewItemTypeButton;
use SilverStripe\Forms\GridField\GridFieldConfig_RecordEditor;

$config=GridFieldConfig_Base::create(10);
$config->addComponent(new AddNewItemTypeButton($yourOptionsMap, 'buttons-before-left'));
$config->addComponent(new ItemTypeDetailForm());

If you are managing a versioned object you must override the item request class using:

use WebbuildersGroup\GridField\ItemType\VersionedItemTypeDetailForm_ItemRequest;

$detailForm->setItemRequestClass(VersionedItemTypeDetailForm_ItemRequest::class);

Note: All options in the type dropdown must be decendents of the model class.
