loadOnDemand Boolean (default: true)

Indicates whether the child DataSources should be fetched lazily when parent groups get expanded. Setting this to false causes all child DataSources to be loaded at initialization time.

Note: when initializing the widget from an array (rather than from a HierarchicalDataSource instance), this option defaults to false, rather than true.

Example - force lazy loading of sublevels

<div id="treeview"></div>
<script>
$("#treeview").kendoTreeView({
  loadOnDemand: true,
  dataSource: [
    { text: "foo", items: [
      { text: "bar" }
    ] }
  ]
});
</script>
