How to create Window on top of Layout .

A window can be created as usually - dhtmlxWindows/samples/02_viewports/inc/01_default_demo.html

Please provide the sample to reproduce the problem. It isn’t clear from the description

my code:

dhxLayout = new dhtmlXLayoutObject("parentId", "3U");
w1 = dhxLayout.dhxWins.createWindow("aaaaaaaaaaa", 50, 80,500,600);
w1.attachURL("http://www.google.com");
 w1.center();
w1.setText("google");
w1.attachObject("parentId");

or

dhxLayout = new dhtmlXLayoutObject("parentId", "3U");
dhxWins = new dhtmlXWindows();
w1 = dhxWins.createWindow("aaaaaaa", 50, 80, 640, 480);
w1.attachURL("http://www.google.com");
w1.center();
w1.setText("google");
w1.attachObject("parentId");

Comment line w1.attachObject(“parentId”); to solve the problem.

As you use the same container here
dhxLayout = new dhtmlXLayoutObject(“parentId”, “3U”);
