I built a multi step form. In the last step before the opt-in, I ask the postcode. It is a required field. It should also remain a required field. The animation (interaction) starts with the click on the button. At the moment, it is a Submit-Button.
How can I not start the animation until the user has completed the field? The user must fill out the field before the animation starts.
