Creating Menu Items and Sub Items

Creating Menu Items and Sub Items


I'm encountering issues with creating menu and sub menu items through dragging then from the interfaces area. This worked well at one point but just stopped working again.

The deployed version on a browser displays correct, but not in the development environment. In the development environment when I attempt to switch the web block to show its content (sub-menu items) a message appears as per the screen shot.

Please find the attached screen shots plus the OML file.
