Form Builder: move elements anywhere in the schema

[papadopan]

Feature request

What is the expected behavior?

Currently users are possible to move the boxes and re-order them only in a sibling level

There is a possibility in the event of great change to move a huge block of them in a different path

What is motivation or use case for adding/changing the behavior?

How should this be implemented in your opinion?

Are you willing to work on this yourself? yes
