I wasn't sure if I should buy the pro version because support seemed to be lacking. But I'm really glad I got it!
I needed a dropdown menu to dynamically display all posts from a custom post type. I also needed a dropdown menu to display all child pages of a parent page. Gecka Submenu Pro worked great for both situations!
The CPTs were created using Pods and AgentPress Listings, so this works great with them.
Thanks again for the great plugin! Just maybe work with support a bit more, and I think it will be fantastic.
