After adding preference for the class
<preference for="Magento\Customer\Block\Adminhtml\Group\Edit\Form" type="Vendor\Module\Block\Adminhtml\PathToFile" /> Add below code in it
$fieldset->addType( 'some_thing', 'Vendor\Module\Block\Adminhtml\Renderer\ClassName' ); $field = $fieldset->addField( 'some_thing', 'some_thing', [ 'name' => 'some_thing', 'label' => __('Something'), 'title' => __('Something') ] ); In your Vendor/Module/Block/Adminhtml/Renderer/Classname.php
namespace Vendor\Module\Block\Adminhtml\Renderer; class Classname extends \Magento\Framework\Data\Form\Element\AbstractElement { public function getElementHtml() { $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $product = $objectManager->create('Vendor\Module\Block\Adminhtml\Path to your grid file')->getBlockGrid(); //can inject also I used ObjectManager for testing $html = parent::getElementHtml(); $value = $this->getValue(); $html.=$product; return $html; } } ?> In your Grid file at Vendor/Module/Block/Adminhtml/Path to gridfile.php
<?php namespace Vendor\Module\Block\Adminhtml; class Grid extends \Magento\Backend\Block\Widget\Grid\Extended { protected $productFactory; public function __construct( \Magento\Backend\Block\Template\Context $context, \Magento\Backend\Helper\Data $backendHelper, \Magento\Catalog\Model\ProductFactory $productFactory, \Magento\Framework\Registry $coreRegistry, array $data = [] ) { $this->productFactory = $productFactory; $this->_coreRegistry = $coreRegistry; parent::__construct($context, $backendHelper, $data); } /** * @return void */ protected function _construct() { // parent::_construct(); // $this->setId('hello_tab_grid'); // $this->setDefaultSort('entity_id'); $this->setUseAjax(true); } /** * @return Grid */ protected function _prepareCollection() { $collection = $this->productFactory->create()->getCollection()->addAttributeToSelect("*"); $this->setCollection($collection); return parent::_prepareCollection(); } /** * @return Extended */ protected function _prepareColumns() { $this->addColumn( 'entity_id', [ 'header' => __('Product Id'), 'sortable' => true, 'index' => 'entity_id', 'header_css_class' => 'col-id', 'column_css_class' => 'col-id' ] ); $this->addColumn( 'name', [ 'header' => __('Product Name'), 'index' => 'name' ] ); $this->addColumn( 'sku', [ 'header' => __('Sku'), 'index' => 'sku' ] ); return parent::_prepareColumns(); } /** * @return string */ public function getGridUrl() { return $this->getUrl('moduler/*/action', ['_current' => true]); } public function getBlockGrid() { if (null === $this->blockGrid) { $this->blockGrid = $this->getLayout()->createBlock( '\Vendor\Module\Block\Adminhtml\Path to your grid file', 'category.product.grid' ); } return $this->blockGrid->toHtml(); } } 
In order to add custom grid in customer group edit form you need to override the controller and custom block to render grid in it.
Create custom module for it
Vendor/Module/etc/di.xml
<?xml version="1.0" ?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <preference for="Magento\Customer\Controller\Adminhtml\Group\NewAction" type="Vendor\Module\Rewrite\Magento\Customer\Controller\Adminhtml\Group\NewAction"/> </config> Vendor/Module/Rewrite/Magento/Customer/Controller/Adminhtml/Group/NewAction.php
<?php /** * Copyright © Dev All rights reserved. * See COPYING.txt for license details. */ declare(strict_types=1); namespace Vendor\Module\Rewrite\Magento\Customer\Controller\Adminhtml\Group; class NewAction extends \Magento\Customer\Controller\Adminhtml\Group\NewAction { /** * Edit or create customer group. * * @return \Magento\Backend\Model\View\Result\Page */ public function execute() { $groupId = $this->_initGroup(); /** @var \Magento\Backend\Model\View\Result\Page $resultPage */ $resultPage = $this->resultPageFactory->create(); $resultPage->setActiveMenu('Magento_Customer::customer_group'); $resultPage->getConfig()->getTitle()->prepend(__('Customer Groups')); $resultPage->addBreadcrumb(__('Customers'), __('Customers')); $resultPage->addBreadcrumb(__('Customer Groups'), __('Customer Groups'), $this->getUrl('customer/group')); if ($groupId === null) { $resultPage->addBreadcrumb(__('New Group'), __('New Customer Groups')); $resultPage->getConfig()->getTitle()->prepend(__('New Customer Group')); } else { $resultPage->addBreadcrumb(__('Edit Group'), __('Edit Customer Groups')); $resultPage->getConfig()->getTitle()->prepend( $this->groupRepository->getById($groupId)->getCode() ); } $resultPage->getLayout()->addBlock(\Magento\Customer\Block\Adminhtml\Group\Edit::class, 'group', 'content') ->setEditMode((bool)$groupId); $resultPage->getLayout()->addBlock(\Vendor\Module\Block\Adminhtml\Group\Grid::class, 'custom_grid', 'content') ->setEditMode((bool)$groupId); return $resultPage; } } Vendor/Module/Block/Adminhtml/Group/Grid.php
<?php namespace Vendor\Module\Block\Adminhtml\Group; class Grid extends \Magento\Backend\Block\Widget\Grid\Extended { protected $productFactory; public function __construct( \Magento\Backend\Block\Template\Context $context, \Magento\Backend\Helper\Data $backendHelper, \Magento\Catalog\Model\ProductFactory $productFactory, \Magento\Framework\Registry $coreRegistry, array $data = [] ) { $this->productFactory = $productFactory; $this->_coreRegistry = $coreRegistry; parent::__construct($context, $backendHelper, $data); } /** * @return void */ protected function _construct() { // parent::_construct(); // $this->setId('hello_tab_grid'); // $this->setDefaultSort('entity_id'); $this->setUseAjax(true); } /** * @return Grid */ protected function _prepareCollection() { $collection = $this->productFactory->create()->getCollection()->addAttributeToSelect("*"); $this->setCollection($collection); return parent::_prepareCollection(); } /** * @return Extended */ protected function _prepareColumns() { $this->addColumn( 'entity_id', [ 'header' => __('Product Id'), 'sortable' => true, 'index' => 'entity_id', 'header_css_class' => 'col-id', 'column_css_class' => 'col-id' ] ); $this->addColumn( 'name', [ 'header' => __('Product Name'), 'index' => 'name' ] ); $this->addColumn( 'sku', [ 'header' => __('Sku'), 'index' => 'sku' ] ); return parent::_prepareColumns(); } /** * @return string */ public function getGridUrl() { return $this->getUrl('hello/*/helloGrid', ['_current' => true]); } } This is just a overview to show custom grid, for full implementation and operations on custom grid please follow this blog post
Thanks!
