Highlight in menu nav

Hi there,

Something WordPress can become confused between custom post types and the regular post type.

I did some searching on this and didn't find any specific fixes.

Can you try adding the URL to your Blog as a "Custom Link" in "Appearance > Menus".

Let me know if that helps or not :)

Hi Tom ,

now I have used a custom URL. The "Vehicles" tab is now highlighted but also the "News" tab.

Probably "News" is highlighted as it is in both sides is an archive.
Here is now to understand how the active classes will be awarded for the menu nav and accordingly may intervene from the archives vehicles or single vehicles.

It is devinitiv a problem with the Theme. If I used a standard WPTheme the "blog" tab is not highlighted.

That means we have to change anything so that the Custom Posts get display highlighted in the right way.

Hi Tom,

with this little Code I can highlight the "Fahrzeuge" tab in navigation

function custom_active_item_classes($classes = array(), $menu_item = false) {
        global $post;
        $classes[] = ($menu_item->url == get_post_type_archive_link($post->post_type)) ? 'current-menu-item active' : '';
        return $classes;
}
add_filter( 'nav_menu_css_class', 'custom_active_item_classes', 10, 2 );

But the "News" tab I still active!

Did you try adding the "News" menu item as a "Custom Link" and not a "Page"?

GP makes use of three WordPress classes:

.current-menu-item
.current-menu-parent
.current-menu-ancestor

These are built into WP, but I have a feeling that one of them is rarely used anymore and is the cause of this issue.

Can you link me to one of your single custom post types templates so I can see which class is causing the News item to be highlighted?
