| Param | Type | Details |

| item | Object | The item which layout is updated |
This method is useful when you want to update only a specific item, instead of whole tree structure. The update is instant, resulting in great performance.
This method does not return a value.
Supported in: v1.0.
In this example we are showing how to call updateLayout method. In current example the currently selected item will update its layout.
$(document).ready(function() {
// Create an instance of TreeView widget
var $tree = $('#treeview').treeview();
var getCurrentSelection = function(){
return $tree.treeview("option", "selectedItem");
}
$tree.treeview("updateLayout", getCurrentSelection());
});
