In your experience, is it a good or bad idea to disable the "Submit" button in a form if there is a pending error? (Of course, with a live inline validation in place)?

The issue with the idea is that disabling a button doesn't really give any feedback to customers on what's missing. But then live validation is supposed to catch these issues, right?

Just found a great section on the downsides of the techniques in @adambsilver’s book on Form Design Patterns:

– First, users are left wondering what’s actually wrong with their entries.

– Second, disabled buttons are not focusable, which makes it hard for the button to be discovered by blind users navigating using the Tab key.
– Third, disabled buttons are hard to read as they are grayed out.”
