Tree with button below

Hi,

I want to have a dhtmlx window contains a dhtmlx tree. At the bottom of the window, i want to have a button ‘Run’.

The idea is users select tasks they want to run (tree with checkbox shows all the tasks), then click 'Run ’ button to execute and the window close.

How do i add a button to the bottom of a tree inside a window ?

If you don’t need your window to be resizeble, you can just put your tree and button into differens divs are attached to the window.
