Is there a way to call on just the content of a Page without actually using that Page? [closed]

You can just put something like the following into your template file where you want the form to appear (example of a form called Contact Us):

gravity_form('Contact Us', false, false, false, '', false);

For more info on the false etc, see here: http://www.gravityhelp.com/documentation/page/Embedding_A_Form
