loadOnDemand Boolean|Object
(default: false)
Indicates whether the child DataSources should be fetched lazily when parent groups get expanded. Setting this to true causes loading the child DataSources when expanding the parent node.
Example - force lazy loading of sublevels
<input id="dropdowntree">
<script>
$("#dropdowntree").kendoDropDownTree({
loadOnDemand: true,
dataSource: [
{
text: "foo", items: [
{ text: "bar" }
]
}
]
});
</script>
