I need to take a moment to think about this.updateParentsCheckBoxState(checkbox)

Can you give me some test case? @Jocs

@MrHeer I just think these two cases:

- [x] foo
  
  - [ ] bar
    
    - [ ] zar

---

- [x] - [x] - [x] foo
  
  - [ ] bar
  
  - [ ] zar

Thank you very much.
There is no problem in the first case test.
I don’t understand the second case.

The second will be less use, but it is a legal grammar I think.

I mean I can't understand their logic, I don't known how to update the others status after a task checked

Distinguishing parent-child relationships by DOM structure?

Thank you, I'll try to sovle

@Jocs If distinguishing parent-child relationships by DOM structure, the logic is right.

I would love to have this feature in Mark Text.

@MrHeer Is there an issue that is blocking this PR from your side?

If it is because of the failing CI build, it seems to me that it is failing due to an PR-independent build error related to vscode-ripgrep.

@renehummen The author think my code had some problems, but I'm not clear that.

@Jocs If distinguishing parent-child relationships by DOM structure, the logic is right.

@MrHeer Can this PR also handle the following cases?

- [ ] task 1
  - [ ] subtask 1.1
    - [ ] subsubtask 1.1.1
    - [ ] subsubtask 1.1.2
  - [ ] subtask 1.2
    - [ ] subsubtask 1.2.1
    - [ ] subsubtask 1.2.2
- [x] task 2
  - [x] subtask 2.1
    - [x] subsubtask 2.1.1
    - [x] subsubtask 2.1.2
  - [x] subtask 2.2
    - [x] subsubtask 2.2.1
    - [x] subsubtask 2.2.2

... where toggling task completion leads to the following behavior:

1. Toggling subtask 1.1 to complete, toggles completion of subsubtasks 1.1.1 and 1.1.2
2. Toggling subsubtasks 1.2.1 and 1.2.2 to complete, toggles completion of subtask 1.2
3. (1) and (2) combined also toggle completion of task 1

I am not entirely sure what the best behavior for untoggling would be. I would suggest:

3. Untoggling completion of subtask 2.1 toggles subsubtasks 2.1.1 and 2.1.2 to incomplete
4. Untoggling competion of subsubtasks 2.2.1 and 2.2.2 toggles subtask 2.2 to incomplete
5. (3) and (4) combined also toggle task 2 to incomplete

This PR handle it like this:

@MrHeer I think the best option would be to add a settings option for this feature, so the user can decide whether the feature should be enabled or all checkboxes must be checked.

@fxha Thank you, I will add a settings option for this feature when I have time.

@fxha Hi, I have updated, can you review?

@MrHeer Sorry for reply so late, Did you have finished this PR, so we can review it?

Yes, you can review it.

I have reviewed the code again, and run it locally, and found a small problem. When initializing the editor, autoCheck was not passed to the editor, causing autoCheck to use the default values in muya instead of user settings.

@Jocs Thank you very much. I have updated, please review again.

@MrHeer Thanks very much for your contribution!

It's my pleasure.
