To hide certain menu items based on the security settings or roles, do the following:
Step 1: In the Application Explorer, go to the Menu Panels folder and select Menu.ascx. This displays the menu in the Design tab.
Step 2: Select Tools, Page Properties to display the Page Properties dialog.
Step 3: Click Show Tree to show all the controls on the left.
Step 4: In the tree, you will see several items like Menu1MenuItem and Menu1MenuItemHilited. If you select each item, you will be able to see the text displayed for the menu on the Display tab.
Step 5: Select the menu item you want to secure, select the Security tab, and set the security appropriately.
Please note that you should also set the Security settings for the Hilited version of the menu item. The Hilited version displays the highlighted version of the menu item when the page displayed is the same as the one you would go to when you click the button.
