Users of my website use a form to receive a report by e-mail (pdf) or by classic postal mail and i would like that postal mail fields appear only if users check a checkbox before.
Didn't find in the forum with my poor english if it's possible or not and how to do it if possible. Could someone help me and put me on the right way ?
Essentially what you do is, add all possible form fields to the form.
Add jQuery at startup that hides certain 'optional' form fields and use jQuery event handlers to sit ontop of e.g. a checkbox to (when enbaled) show these previsouly hidden fields...quite simple.
