Force highlight a CSS Menu Writer menu item
I was wondering if it is possible to force highlight a menu item?
I have a menu with 7 main items, of which 2 have sub menus. All are working correctly, but I have a page which is not accessible through a sub menu, so it doesn't highlight the top menu item when the page is loaded.
e.g. the menu title is "Top Level", and the main page is "top_level.php". I then have a page which is "top_level2.php" which is categorised under "Top Level" but does not require a sub menu. I would like the "Top Level" menu to be highlighted when "top_level2.php" is selected. Is this possible?
