Copy your campaign code
Paste your campaign code into Drupal
Just under the input area there is a dropdown menu labeled Text Input. Change this option to Full HTML. If you leave the default as Filtered HTML the entry form will not display when you publish this article or page.
Publish your Drupal blog post
You should be able to Preview your Article or Page, though sometimes when in Preview mode the entry form is shown quite far down the page. Be sure to check this again once you have clicked on Publish to set your entry form live within the blog post. That’s it!
