We should add validation to this input, and the create button should be disabled as long as the input is invalid

[oliviertassinari]

the create button should be disabled

I would be in favor of never disabling a submit button, but to make it a noop and to show the error when pressed.

I would be in favor of never disabling a submit button, but to make it a noop and to show the error when pressed.

I imagine we could decide on a case-by-case basis.

• A single input + submit button in a dialog: we should show a validation message as soon as invalid input is typed, and disable the button to communicate that nothing will happen when clicked.
• a large form with multiple inputs that can scroll: I think not disabling the button and showing the error when pressed (as you described) makes sense
