This is the Google Form that I use to develop and test the WordPress Google Form plugin.
[gform email=’on’ prefix=’wpgform_mc_’ form=’https://docs.google.com/spreadsheet/embeddedform?formkey=dEJ6cTZidDJPY3B3aW5XeEI4RWVsNnc6MQ’ validation=’on’ captcha=’on’ columns=’2′]
The following shortcode produces the sample form displayed on this page:
[gform email='on' prefix='wpgform_mc_' form='https://docs.google.com/spreadsheet/embeddedform?formkey=dEJ6cTZidDJPY3B3aW5XeEI4RWVsNnc6MQ' validation='on' captcha='on' columns='2']
