TreeGrid: only Leaf-Icons no matter what type

Suite and Optimus Suite 5

Hello,

as you can see attached my TreeGrid implementation only shows leaf icons.
I correctly marked the different nodes with $row->set_kids(true/false); .

Any ideas?

Thanks in advance
Peter

You may define the “folder icon” to your row right in your data:

   <cell image="folder.gif">Honda</cell>

Just check if you have such image file in your images directory.
