+You can set a function to override if a node can be selected. The function gets a node as parameter, and must return true or false.
+
+For this to work, the option 'selectable' must be 'true'.
+
+{% highlight js %}
+// Example: nodes with children cannot be selected
+$('#tree1').tree({
+    data: data,
+    selectable: true
+    onCanSelectNode: function(node) {
+        if (node.children.length == 0) {
+            // Nodes without children can be selected
+            return true;
+        }
+        else {
+            // Nodes with children cannot be selected
+            return false;
+        }
+    }
+});
+{% endhighlight %}
