You can easily turn on/off the node selection feature by setting selectEnable property.
If you want to select multiple nodes you can set multipleSelectEnable to true.
In the case that you need to enable selection of some nodes and disable others, you can use selectDisableIds property.
<?php
require $KoolControlsFolder."/KoolTreeView/kooltreeview.php";
$treeview = new KoolTreeView("treeview");
$treeview->scriptFolder = $KoolControlsFolder."/KoolTreeView";
$treeview->imageFolder=$KoolControlsFolder."/KoolTreeView/icons";
$treeview->styleFolder="default";
$treeview->showLines = true;
$root = $treeview->getRootNode();
$root->text = "Hello, I'm root ;)";
$root->expand=true;
$root->image="tree.gif";
//Multiple Select
$treeview->Add("root","multiple","Select Multiple Nodes",true,"oTasks.gif","");
$treeview->Add("multiple","multi1","Press Ctrl",true,"ball_glass_blueS.gif","");
$treeview->Add("multiple","multi2","And Press Left Mouse",true,"ball_glass_redS.gif","");
$treeview->Add("multiple","multi3","To Select Us :)",true,"ball_glass_greenS.gif","");
//Select Disable
$treeview->Add("root","disable","Select Disable Node",true,"memobook.gif","");
$treeview->Add("disable","dis1","<span style='color:#888'><i>You can't select me :|</i></span>",true,"person.gif","");
$treeview->Add("disable","dis2","<span style='color:#888'><i>Me, too :(</i></span>",true,"person.gif","");
$treeview->Add("disable","dis3","You can select me :)",true,"workerS.gif","");
$treeview->selectEnable = true;
$treeview->multipleSelectEnable = true;
$treeview->selectDisableIds = "dis1,dis2";
?>
<div style="padding:10px;">
