Suppose I have a checkbox custom field "Tests", it following options:
[ ] Test A
[ ] Test B
[ ] Test C
[ ] Test D
[ ] Test E
[ ] Test F
...until test Z (Note it is a long list)
Users asked me to implement options levels like this (indented):
[ ] Group 1
[ ] Test A
[ ] Test B
[ ] Group 2
[ ] Test C
[ ] Test D
[ ] Test E
[ ] Test F
...etc
So users can select the main groups, and all group items will be marked by default to make the selection faster, and (very important) to visualize each group label.
If possible it could be collapsed:
I found an example:

Is it possible to customize the checkbox field using scripts to have this behaviour?
Is there some addon for this kind of checkbox field ?
