Make submit button disable optional

[X-Tender]

Feature Request

Is your feature request related to a problem? Please describe. Currently when you click the "submit" button it gets disabled via JS. Now I implemented a client side validation and therefor I have to add a workaround to "re-enable" the submit button when the form was invalid to give the user the posiblity to resubmit it.

Describe the solution you'd like Maybe via a data attribute on the submit button? like "data-no-disable-on-submit"
