Hi Ive used the standard Data grid and want to populate a drop down box to force users to use information already in the system, when i add records by using the new record tab. I want to populate it with a attribute from a different entity. Pls Help

You can create a reference to the desired object, and show one of its attributes in a reference selector (drop down). For more information see the documentation
