Add Extra Text Field

Hi,

We are wondering if anyone has a solution to this requirement. We want to allow a user to add another text field at the click of a button which would extend the input opportunities for say, a job application form.

So a user might have more than 2 qualifications to enter but the current text boxes only allow for 2 qualifications to be entered. Could we put a plus button at the bottom of this which would add a 3rd text field which would also in turn be sent to the email address attached to the WordPress account.

Thanks!
