If You want add to product level custom option look in these file path to add

your code

File Path : vendor/magento/module-catalog/Ui/DataProvider/Product/Form/Modifier/CustomOptions.php

step-1:Defing the variable

const FIELD_IS_DEFAULT_NAME = 'default_radio';

Step-2: in Function getCommonContainerConfig() You have to declare method to

use const variable

children' => [

    static::FIELD_IS_DEFAULT_NAME => $this->getIsDefaultFieldConfig(150)


Step - 3:To which Grid type You want to Assign the Custom option

protected function getSelectTypeGridConfig($sortOrder)

return [

'children' => [

static::FIELD_IS_DEFAULT_NAME => $this-> getIsDefaultFieldConfig(200)



Step 4:To which Datatype You want to Assign the Custom option Should Define


 protected function getTypeFieldConfig($sortOrder)

'indexes' => [



Step 5: code to call getIsDefaultFieldConfig(150) Which defined in step-2

protected function getIsDefaultFieldConfig($sortOrder)
        return [
            'arguments' => [
                'data' => [
                    'config' => [
                        'label' => __('Default'),
                        'componentType' => Field::NAME,
                        'formElement' => Radio::NAME,
                        'dataScope' => static::FIELD_IS_DEFAULT_NAME,
                        'dataType' => Text::NAME,
                        'sortOrder' => $sortOrder,
                        'value' => '0',
                        'valueMap' => [
                            'true' => '1',
                            'false' => '0'

Before These All You need to define in xml for radio go for below Path

File Path:


Add below Code after checkbox

<!--these is added for defining the radio button -->
     <radio class="Magento\Ui\Component\Form\Element\Radio">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="component" xsi:type="string">Magento_Ui/js/form/element/radio</item>
                <item name="template" xsi:type="string">ui/form/field</item>

Step 6:You have create a column under your Database

catalog_product_option_type_value create a column that is defined in step 1.

You can See the radio box

    This solution is offering changing core code which is highly not recommended.
