In addition to the Control Panel Configuration settings, which apply to the menu as a whole, each menu item has settings which can be set individually for that specific item.
To access the Menu Item Settings panel:
1. Visit the Appearance > Menus screen
2. Hover over the menu item you would like to configure and click the Bellows button when it appears.
3. The Menu Item Settings panel will open. After changing the desired settings, click the Save Menu Item button in the upper right to save the settings for that specific item. The Bellows menu item settings will be saved via AJAX independently from any other menu settings, so there is no need to re-save the entire menu to update the Bellows menu item settings.
