The Plugin does not support validation for multiple forms on the page.

[reatlat]

If I have multiple forms on the page, error messages appear only on the first form, meantime the second form may add error class to input, but error message not appear.

Is any way how can I handle second form, or is it a bug?

It should work for multiple forms. Each form needs it's own id. See the examples multiform.html
