jqgrid treegrid with level headers

Question

I Have a TreeGrid with multiple levels I want to add Header for each level (i.e similar to that of subgrid, but i dont want to use it as the columns of subgrid doesnt align with the outer grid).

Answer 1

I would like to drive Porsche for free and that somebody should pay for the fuel additionally. :-) I think it's better that you use existing features of existing product if you want to use free products.

TreeGrid if jqGrid is the kind of grid. If the user collapse node the corresponding rows will be just made hidden. So the grid has column headers and no additional header can be created for tree node.

On the other side Subgrid, especially grid as subgrid, is more flexible. If you create subgrid inside of subGridRowExpanded callback you are free to set alignment, width or just everything from the child grid. You can even place any custom HTML an place of subgrid (see the demo from the answer). In the answer you will find an example how one can adjust width of subgrid if the column of main grid are resized.

So I think that you have to use grid as subgrid to implement your requirements. In any ways you should to write some additional code which implements your exact requirements.
