add country dropdown to customer attribute

[tunnel_dev]

hi everyone, I would like to have some information, or if there is any documentation, on how to add a custom dropdowns attribute for the customer that shows the list of countries. I suppose I have to use the Model Magento \ Directory \ Model \ Config \ Source \ Country somehow, but I haven't found the documentation about it.
Thanks so much.

'country_attribute',
[
'type' => 'varchar',
'label' => 'Country',
'input' => 'text',
'required' => true,
'visible' => true,
'user_defined' => true,
'position' => 999,
'system' => 0,
]

Hello @tunnel_dev 

Please try the below solution:

$customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, 'country_attribute',
    [
        'type' => 'varchar',
        'label' => 'Country',
        'input' => 'select',
        'required' => true,
        'visible' => true,
        'user_defined' => true,
        'position' => 999,
        'system' => 0,
        'source' => 'Magento\Directory\Model\Config\Source\Country',
    ]

I hope it helps.

Thanks for the replies.

the attribute appears correctly as dropdown, but from the admin the options are empty, it does not automatically load the list of countries. Here is the code used. Maybe I need to change something in the $ attribute = $ this-> eavConfig-> getAttribute (Customer :: ENTITY, 'country_attribute'); statement?

Thanks a lot

$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(
            \Magento\Customer\Model\Customer::ENTITY,
            'country_attribute',
            [
                'type' => 'varchar',
                'label' => 'Custom Country',
                'input' => 'select',
                'required' => true,
                'visible' => true,
                'user_defined' => true,
                'position' => 999,
                'system' => 0,
                'source' => 'Magento\Directory\Model\Config\Source\Country',
            ]
        );
        $attribute = $this->eavConfig->getAttribute(Customer::ENTITY, 'country_attribute');
        $attribute->setData(
            'used_in_forms',
            ['adminhtml_customer','customer_account_edit','customer_account_create']

        );
        $attribute->save();

Hi Marcus,

I have already followed that tutorial, the dropdown field is created correctly, but although I have set the source with the model which therefore already contains the getAllOptions () method, the dropdown is empty, the list of Countries is not preloaded.

I set this source:

'source' => 'Magento\Customer\Model\ResourceModel\Address\Attribute\Source\Country'

I don't understand what the missing detail is.

Thanks al lot.

the problem was only the user_defined value, if set to false the country list is preloaded correctly, otherwise the Model indicated for the source parameter is ignored.
