Hi Maxim, 8.0.0-SNAPSHOT is deploying; you should now be able to supply your own callback as follow:
@Override public void onConfigure(JQueryBehavior behavior) { behavior.setOption("select", "function(...) { ... }"); } Please refer to jQuery UI or Kendo UI doc for usage/arguments. Please also note that an ajax behavior is still bound to the component (but not used), that's ok if you have only one menu. But if you have dozen, you may consider having your own menu implementation... Thanks & best regards, Sebastien.
