How can I achieve State and Country field functionality in Admin under customer Account Information?
I have referred this link to create in front-end
In customer Registration form got the functionality.
I did a small change in custom attribute I used Magento\Catalog\Model\Product\Attribute\Source\Countryofmanufacture source to list the country. For state I refereed the above link.
In Admin I don't know how to achieve state functionality.
I need to achieve state list if options are available and text field if not.
Can someone help me with this I referred lost of blog and Stack Exchange but can't find a single post that explains the workflow to achieve in admin.
