Por favor, chequee esto.

Paso 1: agregue el siguiente código en su formulario de interfaz de usuario

 <fieldset name="assign_products">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="label" xsi:type="string" translate="true">Assign Products</item>
                <item name="collapsible" xsi:type="boolean">true</item>
                <item name="sortOrder" xsi:type="number">40</item>
            </item>
        </argument>
        <container name="assign_products_container" >
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="sortOrder" xsi:type="number">60</item>
                </item>
            </argument>
            <htmlContent name="html_content">
                <argument name="block" xsi:type="object">Namespace\Module\Block\Adminhtml\Products\Edit\AssignProducts</argument>

    }
</script>
<!-- @todo remove when "UI components" will support such initialization -->
<script>

Paso 4: Copiar vendor/magento/module-catalog/view/adminhtml/web/catalog/category/assign-products.js aNamespace/Module/view/adminhtml/web/products/

Paso 5: crear Grid.php Namespace/Module/Controller/Adminhtml/Products

namespace Namespace\Module\Controller\Adminhtml\Products;

        $this->_objectManager->get('Magento\Cms\Model\Wysiwyg\Config');
        return $storeModel;
    }   


}

Paso 6: crear Product.php Namespace/Module/Controller/Adminhtml/Products

namespace Namespace\Module\Controller\Adminhtml\Products;


abstract class Product extends \Magento\Backend\App\Action
{
    /**
     * Authorization level of a basic admin session
     *
     * @see _isAllowed()
     */
    const ADMIN_RESOURCE = 'Namespace_Module::item_list';
