👨‍💼 Great! Now when the user submits the form, this extra information will be available in the submission without the user needing to supply it. Well done!

🦉 A common question here is whether you can supply complex data structures as hidden input values, and you definitely can. You can either provide multiple hidden inputs, or just stick JSON in your hidden input like so:

<input
	type="hidden"
	name="order"
	value={JSON.stringify({ sandwich: 'tuna' })}
/>

Then the backend could parse that JSON from the order form field. This can be very useful if you're using a library that doesn't render form elements, but you want to send the user's selections to the backend as a part of your form using your own form elements.
