Define a form element type "address"

I would accept such a patch.

As I don't want to use Eform ..

I'm missing that too ... and I guess this would be a FormElement.

This feature was also requested for drupal.org/project/addressfield at #970048: Define and use addressfield as a form element type

Thanks. Adding that as a related issue for more visibility.

Cheers,

Done! :)

FYI: this might not be working properly. See #2848747: Address form element doesn't work on forms without #tree => TRUE

I have it working on multiple forms, Commerce and non-Commerce. We need to identify what makes that issue different.

Good to know, thanks. I didn't want to re-open this issue, just add a link for interested parties.

#2848747: Address form element doesn't work on forms without #tree => TRUE is now marked as a child of this, so it doesn't need to be more generally "related" in here...

@bojanz this works fine on custom form except the validation part as constraint validation only works for entity not custom form
