Block transition of sub-task based on parent's status

[Asher Gilmour]

Our workflow consists of the following:
In Design -> In Review -> To Do -> In Progress -> Done

The aim is to block the possibility of moving a sub-task to "to do" if the parent is still in the status of "In Design"

Hi @Asher Gilmour Welcome to Atlassian Community!

You need to add "Parent Status Validator" on Sub-tasks workflow to block sub-tasks issue transition to "To Do" status.

Is that standard or an add on? I can't see it

Jira Workflow Feature no need of any plugin. Available in Company Managed Project only.

OK!

Found it
It seems it is not accessible from the new editor, only from the old one (unless you know where)

Thanks @Vikrant Yadav
