Publish with an iframe – (Inline Frame):

If you’d rather display the form in an inline frame, or if your server doesn’t support the default publishing method, add the iframe attribute to your tag.

For instance, a benefit to using an iframe would be to avoid conflicting CSS rules between the parent site and the embedded form.
[formassembly formid=123456 iframe=1]


[formassembly formid=123456 server=”https://your.server.tld” iframe=1]

Publish a Workflow:

[formassembly workflowid=1234]

Add Style:

It is possible to add CSS to your shortcode to control the size of the form/iframe in the page. For example, you can define the width:
[formassembly formid=123456 iframe=1 style=”width: 300px !important;”]

  1. Upload to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Place [formassembly formid=NNNN] shortcode in your post.

I was glad to see that this plugin does more than just insert an iframe on the page. However, when you use the shortcode it wraps the entire page in it's own wrapper and applies its own styles to all of your page content. So if you try to add any text above and below the form, you'll find that it's now in a tiny 13px and generally looks terrible. It doesn't have an option to turn styling off, you can override it with your own CSS, but it's a pain.

Just place the shortcode anywhere you want the form to appear and replace the ID with your own from TFA.
