Possible to attach INPUT element to multiple forms?

Question

Is it possible to attach an input element to more than one form? I know HTML5 allows you to specify a form an element belongs to by form's ID. But is it possible to attach it to like multiple ID's?

It seems nice to do all that without any javascript/JQuery, which is the alternative.

Answer 1

No, a form control can be associated with only one form.

From w3c specification:

If a reassociateable form-associated element has a form attribute specified, then that attribute's value must be the ID of a form element in the element's owner Document.

You can use a single, large form and decide (on the server) which inputs to pay attention to based on which submit button was pressed.
