This example uses a trick. It uses a `<div>` tag like if it was an input. That input uses a custom validator that succeeds only if one of the groups (here `"block-1"` and `"block-2"`) validate with the `force` option set.

Note that the `<div>` contains the fields in question. This way, events like `change` or `input` generated when the user fills in these fields will bubble up to the div and revalidate the custom field.
