Question on Adaptive Form Fragments

We have recently started using Fragments in our Adaptive forms. I noticed that when I create a new fragment, the jcr property (fd:version) defaults to 1.1. However, fragments from the Core form component examples project are set to 2.1. What controls this version assignment? creating a fragment with 1.1 version does show it under /assets.

Additionally, after creating a fragment, the components available are all sourced from fd/af/components/. How can I configure this to point to my project instead? I also do not see a template being selected during fragment creation, so I’m unsure how the allowed components are determined.

Thanks,

Abhishek
