For complete control over Response Pro’s Menu, we highly recommend using the WordPress menu system. By default, any page you make becomes a link in the menu. However, when you create a custom menu you need to manually update your menu for greater control. Response Pro allows for two custom menus, one in the main navigation and one for the Sub-Menu Header Element.
To begin creating your own custom menu, visit Appearance > Menus while logged into your WP admin. Assign a name for your menu (navigation for example) and begin adding your menu items by using the options available to you in the left-hand menu. You can either make your own custom links by entering in the URL and the Label (the text that will actually show up in the menu), or by selecting and adding currently existing pages, posts or category and tag archives.
You may then drag and drop each item to re-order them, or to create your own custom dropdown menus by dragging pages under a parent page and nested them offset to the right. Once you are done creating your menu, select it from the Header Menu dropdown list and press Save Menu. Now your new custom menu will appear in your Menu.
