Hi,
I’m sorry, but it is not possible to insert other shortcodes into the form fields. The majority of plugins includes its own javascript code, the same programming language used by the CFF for rendering the forms, and injecting the code of third party plugins can brake the forms.
A possible solution would be import the code after rendering the form, for example, suppose you insert the shortcode directly in the webpage into a DIV tag, as follows:
<DIV id="thirdParty" style="display:none;">[annotator_pro name="atrium-4"]</DIV>
and then in the form, you can insert a “HTML Content” field, with the piece of code:
<DIV id="myContainer"></DIV>
<SCRIPT>
setTimeout(function(){
jQuery('#myContainer').html(jQuery('#thirdParty').html());
}, 5000);
</SCRIPT>
Best regards.
