Better Menus not displaying

Hi,
I'm wondering if anyone has used Better Jump Menus and tried to add them to a panel > variant > content. I've tried with no success. I can add anything else to the variant, but a Better Jump Menu item won't bite.

If your not aware of Better Jump Menus (project/module), it automatically creates Jump Menus out of all of your menus and creates blocks to place in your site.

Better Jump Menus: http://drupal.org/project/jump_menu

Thanks for your help.
