Apply SysLookupMultiSelectCtrl class in grid field

Hello All,

I have requirement to select multiple option from lookup control in two way. One is from dropdown that dropdown i have added on form and other is select multiple options from grid field.

I am able to achieve multiple selection option for dropdown through SysLookupMultiSelectCtrl class. However, I am not able to do same thing with grid field.

Is there workout how to select multiple options from grid field lookup.

Thanks In Advance.
