Thanks for contacting us and for your interest in RadControls for WinForms.
I think that in your case it would be better to use the RadMenu
control. You can read more about RadMenu
The idea is to add only first-level items to the control, bind to their click events and implement your logic in the handlers of these events.
You can write back anytime you need further assistance or have any further questions.
