Ok.. you have create your main menu and you want to disable it ?

If yes.. There exist a SKIP FOR clause (used to disable items on the menu) that you can create an expression to disable/enable it !

---

If no.. (all that you want is exchange an old menu for a new one) If you created your menu at MENU DESIGN AREA just go:

VIEW / GENERAL OPTIONS / LOCATION / REPLACE
