How to attach dhtmlXList to dhtmlXLayoutObject

how to attach dhtmlXList to dhtmlXLayoutObject.
I tried adding with following way :-

myLayout = new dhtmlXLayoutObject({
parent: document.body, // parent container
//parent: “layoutObj”, // parent container
pattern: “2U” // layout’s pattern
});

	myList = new dhtmlXList({
			container:"data_container",
			template:"#Package# : #Version#<br/>#Maintainer#"
		});
	myList.load("./data/data.xml");

	myList = myLayout.cells("a").attachList(myList);

But the issue with above approach is list is not shown , it is behind the layout. Please help.
