Sometimes the basic grid just isn't enough.

You might want to use jqGrid to build report specs by selecting a number of items from a single table to include in the report. Or you might want to use jqGrid as a mover where you can select a number of items in one grid and move them to another, for reconciling an account, for example. Multiselect grids are ideal for those purposes.

And there are times when you might need to deal with data within a parent-and-child structure: jqGrid offers three ways of doing that, as Subgrids, Master/Detail grids, and Treegrids, the last of which lets you drill down even further, past the Children to the Grandchildren, and beyond.
