Hi Yoga,

Found below the solution of what you where looking for.
I think the way you had your ul formatted was displaying correctly but it 
was not correct found below the way I did it by nesting the ul (child) into 
the li(parent)
I applied an id to the ul (root) to make it easier to access in the DOM
I put an onclick function on each checkbox who contain a list of country (I 
could have made a recursive function who was making this work with any 
checkbox and child of this one if you need this functionnality let me know)

Regards

Laurent
