I have inherited a wordpress website, which has been highly customised. This is very frustrating, particularly when you want to change things. Anyway, the main navigation menu has not been created in the menu area so I can't add sub-pages. The main menu has been coded into the header.php and sub-pages are shown in a separate menu which has been coded into the sidebar.php. For example, when you click on 'About us' the sub-ages aren't shown at the top - they are shown in the sidebar in a green widget. This is not working for us. I want the sub-pages to appear in the main menu when you hover over it.
Can anyone help me? I have an adequate skill level - not advanced.
