Form

Description

I need the submit button of form to be disabled till all the form fields are valid. As soon as all user inputs are valid, it should be enabled.

The underlying issue is that aync-validator (used in element form) is... asynchronous and the need is to have an synchronous validation method that we can easily use to disable/enable the submit button.

Is there a way to make this behaviour without having to rewrite all the validators handled by async validator ?
