<div style="font-size:12px;">
This example shows the tree grid feature of jqGrid. Currently jqGrid support only a Nested Set Model.<br>
The Adjacency List Model will be supported soon. All you need is to set treeGrid option to true,<br>
and to specify which column is expandable. Of course the data from the server should be ajusted in appropriate way.<br>
