You don't included in the question neither jqGrid definition nor the test JSON or XML data which you use to fill the three grid. I suppose, that you filled the 'expanded' column of the tree grid with true . The hidden column 'expanded' exist in the tree grid for both mode Nested Set Model and Adjacency Model .
If you would set false in the column the tree will be not expended. See here an example.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
