Dependent Subgrid in Dynamics CRM 365 online

Hi All,

I have one requirement in which there is one requirement to create sub-grids.

Lets say, On Quote form , there is one sub-grid (Product Grid 1) related to "products". User can select product from this sub-grid and there is another sub-grid (Lots Numbers Grid 2)  just below the first one  (Product Grid 1) . This subgrid (Lots Numbers Grid 2) is the child of parent grid (Product Grid 1) . when users select product in grid (Product Grid 1)  then its respective Lots details should get visible in grid (Lots Numbers Grid 2) .

Can someone suggest How would I achieve this?

Thanks a lots in advance.

Regards
