Dhtmlx tree grid

Is it possible to make the child of tree to be aligned with its parent ? Im developing an application such that when i select all the child of the tree and click a button it should be aligned along with its parent

The difference between level set by spacer image

so you can change the difference between levels by adjusting spacer image.

To fully remove difference between level you can add next css definition
       div.gridbox img.space{
this will hide all spacer images
