I am trying to use the 'dynamically populate' feature using the shortcode from the Types Custom Post Type plugin, but am not getting any output. The shortcode is displaying on the page when I try to use it outside of the form, but doesn't work when placed inside the form.
Here is an example of the shortcode: [types field="tripnames" class="" style=""][/types] , I also tried [types field="tripnames"][/types] and [types field="tripnames"] but nothing seems to work. Any ideas what could cause this?
