<iframe src="/contact/form.html" style="min-width:260px;width:400px;height:640px;border:none;" frameborder="none" allowTransparency="true" > </iframe>
Please adjust the styles (inline or use a class) as you need it.The CONCAT page on this website is an example to use <iframe> to link a contact form to web pae.
