Menu Types

Setting Menu defaults in Content Types

When you create a new menu - for a different category of products, for instance - you need to enable the content types you want to have appear in that menu, so you can select that menu when you create that content type. The default is 'Main Menu'. To change that:

Administration > Structure > Content Types > (The Content type you want to change - eg Panels) > Edit, then click Menu Settings and check the Menus you want to have available in that Content type. You can also choose which is to be the default if you choose more than one.
