Replace new-record literal link when using MultiClass in grid

[oilee80]

Need to add something like below code.
Main issue with this is that the dropdown would drown would drop below the bottom of the page.
Also the JS doesn't trigger when "Add" is clicked.

Suggestion: Have it appear as a normal "Add" button but when clicked it pops up a list of options

Code:

<?php

use SilverStripe\Core\Extension;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\LiteralField;
use Symbiote\GridFieldExtensions\GridFieldAddNewMultiClass;

/**
 *
 */
class GridFieldDetailForm_ItemRequest_MultiClass_Extension extends Extension
{
    public function updateFormActions(FieldList &$actions)
    {
        $grid = $this->owner->GridField;
        $gridFieldConfig = $grid->getConfig();
        $addMultiClassComponent = $gridFieldConfig->getComponentByType(GridFieldAddNewMultiClass::class);
        if ($addMultiClassComponent) {
            $newRecordField = static::get_new_record_field_from_actions($actions);
            if ($newRecordField) {
                $newRecordField->getContainerFieldList()->removeByName('new-record');
                $newRecordField->getContainerFieldList()->push(
                    LiteralField::create('new-record', $addMultiClassComponent->getHTMLFragments($grid)['buttons-before-left'])
                );
            }
        }
    }

    /**
     * @param FieldList $actions
     * @return LiteralField OR NULL
     */
    private static function get_new_record_field_from_actions(FieldList &$actions)
    {
        $rightGroup = $actions->fieldByName('RightGroup');
        if (!$rightGroup) {
            return null;
        }
        return $rightGroup->getChildren()->fieldByName('new-record');
    }
}

The PR #301 was targetted for resolving this and was merged - I'm assuming that resolves this issue.
