How to prevent dragging out the contents of a child process, but the child process as a whole can still drag?
For example, in BPMN :SubProcess, there are BPMN :StartEvent, BPMN :Task and BPMN :EndEvent. These events cannot be dragged out of BPMN :SubProcess, but the whole BPMN :SubProcess can still be dragged,and within BPMN :SubProcess, they can also be dragged.

Then you need to inject your custom rule module to bpmn-js as an additional module.
Here’s a working CodeSandbox of what you want to achieve: Elements can be dragged unless they are inside a SubProcess: https://codesandbox.io/s/modest-sid-ble3n?file=/src/index.js
Ok, I’ll try it first. Thank you very much!
