Ok. I have replicated this in Plunker. I think it's easy to explain that way.

Second grid which got command button is the one i am talking about.
In second grid first hierarchy, u can sort (Health and PE, Music, English within Green background) nicely. Restrict inside green background.
In second grid second hierarchy by click expand button of subject "Music", u can sort (Personal Learning, The Arts within Blue background) nicely. Restrict inside blue background.
In second grid third hierarchy by click expand button of domain "Personal Learning", the sorting inside third grid (The individual learner, Managing personal learning) does not work. With means it does not restrict inside white background.
As i mentioned,I have used ignore option in sortable. U can see in the plnkr code.
From Grid1-Green i set it to container 'Grid1-Green > tbody >tr ' and ignore 'background-color-light-blue'. This is working nicely.
But when i set Grid2-Blue i set it to container 'Grid2-Blue > tbody >tr ' and ignore 'background-color-white'. This is not working.
Thx in advance again.
