I added theme options page (titled MyTheme) using add_menu_page function, then submenu with add_submenu_page (titled Documentation) and it all works fine. However, when I look at this new menu i created, i see this:
MyTheme (title of admin menu)
- MyTheme (appearing again, with same link, although it wasn't added)
- Documentation (submenu item I added)
Is there a way to change text for 'MyTheme' submenu item so it's not the same as the one above it?
