Ok, would like to make a newsletter form to signup people and collect email addresses.
To keep the form as small as possible I would like to hide the submit button until someone checks a checkbox, that in turns expands the next element email address.

Once the email address field starts gathering information, show the subscribe button.

Any thoughts about doing an action like this?

Thanks,

Larry

You'll have to hack the html and alter the js code to act on the submit button like the other elements are shown or hid. If you make a small form and look at the code you'll be able to see how the form builder applies the conditions to show or hide elements.

There is no way to hide the submit button. You can still accomplish the same thing however simply by making the checkbox required.
