That's pretty easy. Read about jQuery approach to create widgets in DevExtreme http://js.devexpress.com/Documentation/Howto/UI_Widgets/Basics/Create_a_Widget/#UI_Widgets_Basics_Create_a_Widget_Add_a_Widget_jQuery_Approach
For the example specified check out the fiddle http://jsfiddle.net/tabalinas/eerpy2wf/
You can create a list like following:
<div id="list"></div>
$("#list").dxList({
dataSource: employees,
grouped: true,
groupRender: function(group) {
return group.key;
},
itemRender: function(emp) {
return $("<div>").text(emp.name + "(hired at " + emp.hired + ")");
}
});
Just use renderers instead of ko tempaltes.
