Visual Basic - segundo boton desplegable

quisiera saber como se consigue que pinchan con el segundo boton del raton se despliegue una lista con diferentes opciones y como cambiar las opciones, para ponerlas a tu gusto.

Gracias!!

Si lo que quieres es un menu popup, esta es una opcion...
Todo va dentro de la forma
