I have an web site with top-header menu and sidebar menu.
header menu: books music movies (if we are now under music)
sidemenu: blues jazz dance (if we are now under "Jazz")
sidemenu submenu (under jazz): 60's 90's 40's (if we are now at 90's)
I would like to know how can I highlight MUSIC item from top menu (for example by id or class), because wp_nav_menu does't mark this grandparent item in any way...
Please, help!! )
