Basically I'm creating all custom modules for my deployment of sugar. If I remember correctly, 5.1 was supposed to support 1-to-many, with both parent and child being custom modules, directly in module builder. The module doesn't show up in the dropdown list for "Relate to". Am I supposed to use flex relate or deploy the parent module first and then it will show up in the "Relate to" dropdown?

Thanks - the sugar community is awesome!
