Frequently asked questions

HTML checkbox generator
questions.

How are several ticked boxes submitted?

Each ticked checkbox sends its own name and value pair, so the backend sees the same name repeated. The form data parser shows how that looks after decoding.

Can I require at least one selection?

Not with HTML alone. Add a small script that checks the group before submit, and check it again on the server.

Is anything I enter saved or sent to Form Koi?

No. Everything you type or upload stays in this browser tab and is processed locally. Copy or download anything you want to keep before leaving the page.
