SilverStripe elemental base item

This module adds a blank base item which you can use to add sub-items to elements
and a gridfield config which mimics the parent ElementalArea feel for these Items,
allowing an editor to handle these "blocks" like elements.

This module is best used when the goal is to create an element which acts as a
holder for some content "blocks". These blocks might for example be cards,
images in a gallery or slides in a carousel.

Requirements

• SilverStripe ^4
• Silverstripe elemental ^4

Installation

composer require syntro/silverstripe-elemental-baseitem

Documentation

First, simply extend the base item:

use Syntro\SilverStripeElementalBaseitem\Model\BaseItem;

class Teaser extends BaseItem
{
    private static $displays_title_in_template = true;

    private static $db = [
        // Whatever you need for the item to render
    ];

    private static $has_one = [
        'Section' => TeaserCardsBlock::class,
    ];
}

By default, the baseItem has a Title and a ShowTitle field, similar to the
BaseElement in elemental. They will also use the title composite field from the
silverstripe-elemental module. This behaviour can be disabled by setting
displays_title_in_template to false in yaml config or directly in the class.

Then, add the relation to the desired element and configure the gridfield:

use DNADesign\Elemental\Models\BaseElement;
use Syntro\SilverStripeElementalBaseitem\Forms\GridFieldConfig_ElementalChildren;

class TeaserCardsBlock extends BaseElement
{
    private static $has_many = [
        'Teasers' => Teaser::class
    ];

    /**
     * @return FieldList
     */
    public function getCMSFields()
    {
        $this->beforeUpdateCMSFields(function ($fields) {
            if ($this->ID) {
                /** @var GridField $griditems */
                $griditems = $fields->fieldByName('Root.Teasers.Teasers');
                $griditems->setConfig(GridFieldConfig_ElementalChildren::create());
            }
        });
        return parent::getCMSFields();
    }
}
