JSONForms are HTML forms that have hierarchy. They are more than just key-value pairs. They are rich data graphs, with nested objects and arrays. To use it, you arrange your form fields inside containers marked with specific CSS classes. Then with a single function call, your form turns into a deep JSON object.
