Billing Address Dialog Block for React

So you can see it without a click. On load the dialog is a copy drawn in place over the page: a native dialog element that isn't modal, so nothing is trapped, hidden or focused, and the page around the preview keeps working. The Edit billing address button opens the real Dialog, modal, with its focus trap, Escape and focus return, and the copy stays closed until a reload. Both show the same AddressFields component and share the block's state, so what was typed in the copy is there in the real one. In your app keep the Dialog and drop the copy: the "in-place" state, the scrim and the dialog element inside the frame.

Add one object to COUNTRIES: its cells in the order that country writes an address (each with a label, an autofill token, whether it is required, and whether it spans the form), its postal pattern and the sentence to show when it doesn't fit, and its region options if the country has a list. Then say how it prints in printedOf. The four here are only examples of the idea: their patterns are typed in the file and check a code's shape, not that it exists, because nothing is looked up in a postal database. Check the real rules of every country you sell to, or use a service that knows them.

Every field the country marks as required, in the order they appear, and the postal code's shape, each with its own sentence under its field; focus goes to the first problem and the dialog stays open. Optional fields (a second address line, a county) are never flagged. Once a message shows it follows your typing and clears as soon as that field is right. Changing the country starts the region again and checks the postal code again if it had been flagged, since another country means another shape.

It fills the whole form with the company's address, which is in another country than the invoice's, so the country list changes too, then locks every field so it can't drift from it. Turn it off and the fields open again with those values to edit. The company address is a constant in the file; in your app read it from the account.

No. Save address keeps the address in the block's state and reprints the invoice behind the dialog, and the polite status message says nothing was stored or sent. In your app post the fields to your server in save, show its refusals in the field they belong to, and update the invoice from the response, keeping the dialog open until it succeeds.

Yes. The real dialog is named by its title and described by its sentence, focus starts inside it and stays there until it closes, and Escape, Cancel and the close button all return focus to Edit billing address. The trigger is passed to DialogTrigger through render, and the dialog is controlled with open and onOpenChange. The state and prefecture lists are native selects, so a phone shows its own picker; each field's message is tied to it with aria-describedby, the printed address is a labelled address element, and one polite status message reports what changed. The copy shown on load moves no focus; Escape inside it, Cancel and its close button close it and put focus on the header button.
