weird display

I am having the same problem; the directory shows up at the top the page (before the header). It’s theme-related, because it shows up fine in some themes, but not rtPanel.
Example: https://www.nmsta.org/events/2104conference/session-directory/

It’s probably caused by the colorbox script which is not correctly enqueued into the plugin.
As a quick fix, just move the file /colorbox/jquery.colorbox-min.js to /colorbox/js/jquery.colorbox-min.js.

This will probably fix the issue.

Tried it, didn’t work. There was no ‘js’ folder in colorbox, so I created one and moved the file. Didn’t make any difference. Any other suggestions?

Well Colorbox script was not causing that issue (although it is also an issue..)

What is causing this issue is that your theme has a CSS class called .fixed which is conflicting with the Gravity Forms Directory table class (also defined as .fixed), this is why the table sticks to the top of the page.

Just add the following to your shortcode directory definition: tableclass="gf_directory widefat"

example: [directory form="29" tableclass="gf_directory widefat"]

Ahh. You are a genius! Thank you!
