Great Plugin

This plugin works perfectly.
I was looking for a solution like this on the gravity form, but I couldn’t find it on the web.
I’m confident that help tickets can be sent less often by customers. Thank you very much.

Suggested fix:
I’m using v0.2.
When you add a one-line text field in the management screen, the same field option as the search field, that is, “Select Custom Post Type (s)” is displayed. Searching in the front end of a one-line text field doesn’t work, so I think it’s better to remove this option.
