Option editable accepts a boolean or an object. When editable is a boolean, all manipulation actions will be either enabled or disabled. When editable is an object, one can enable individual manipulation actions:

+ +
// enable or disable all manipulation actions
+var options = {
+  editable: true       // true or false

+var options = {

One can specify callback functions to validate changes made by the user. There are a number of callback functions for this purpose:
