Defining a subgrid is essentially the same as setting up the master detail grid as described in our previous example. Again, only a single line of code change is required by calling set_subgrid(). phpGrid also supports single level with multiple subgrids, similar to master grid that has many detail grids.
Starting version 6, nested, drill-down subgrids are supported!
XDue to the calling sequence, the enable_edit() should be called BEFORE set_subgrid() method, or edit properties will be ignored.
