How to make the submit button grayed out until required fields are filled?

Is there a way to have the submit button grayed out until the requires fields on the form are completed?

I've seen this with other online forms - just wasn't sure if it was possible with your system.

Though we do not have a direct way to achieve this, it is possible to hide the Submit button by using few conditions that disable the form to submit.

You can choose Show/Hide Field option from the conditions and set the rules to show when the Submit button to be displayed. Please see the screencast below that can help you with setting up a condition to show the Submit button.

Hope this information helps! If you need any further assistance, please let us know. We will be happy to assist.
