for the task or issues, is there a way to add a checklist that associated with it, and enforce that the taks cannot be finished until all items in the checklist is checked?

Hi Kuiyang,

We do not support checklist because it makes out product becomes more complicated. Some clients need this feature, others do not. Instead of using the checklist, you can create the sub-tasks of a task, mark all sub-tasks done, and we will ask whether you should close the parent task. Does it work?
