Styling the top-level item if it’s active or a child is active is possible with pure CSS. Use the child selector, >, from the top: .sidebar-navigation > ul > .current-menu-item, .sidebar-navigation > ul > .current-menu-ancestor {} If you want to add a new class, you can use the nav_menu_css_class filter. One of its parameters is … Read more
Within each menu item, object_id holds the ID of whatever object the menu item refers to. This will be a post / page / CPT / term ID. If it’s a custom link, the ID refers to itself. (If you want to know what type of object it is, object contains that.) get_queried_object_id() will give … Read more
For flexibility, you could assign the CSS bubblecount class to the corresponding menu item: and then target it with: if( in_array( ‘bubblecount’, (array) $item->classes ) ) $output .= ‘<span class=”unread”>’.my_function_here().'</span>’; in your code snippet above.
To see how such a list can be created look at the code in wp-admin/includes/nav-menu.php. Unfortunately, it is hard coded there, so you have to re-create the code. First, let’s create two menus: We can get these menus in PHP with wp_get_nav_menus() (a wrapper for get_terms()): $menus = wp_get_nav_menus(); print ‘<pre>’ . htmlspecialchars( print_r( $menus, … Read more
I can see a syntax error: replace ‘theme-location’ by ‘theme_location’. Always think about underscores in WordPress variables/functions names 😉 wp_nav_menu() : https://codex.wordpress.org/Function_Reference/wp_nav_menu
Funny, I just ran into this same conundrum a few months back… Background I found it quite bizarre that WordPress applies all manner of CSS classes to menu-items in order to distinguish the current item and its ancestors, but then completely ignores the sub-menus and their relationship with the current item. I wanted a .current-sub … Read more
Use a custom walker. Extend the functions start_lvl() and end_lvl(): class WPSE39005_Div_Walker extends Walker_Nav_Menu { /** * @see Walker::start_lvl() * * @param string $output Passed by reference. Used to append additional content. * @return void */ public function start_lvl( &$output, $depth ) { $output .= ‘<div><ul class=”sub-menu”>’; } /** * @see Walker::end_lvl() * * @param … Read more
You could achieve this with a custom walker function, on your menu. a very simple example: class Walker_WPA82563_Submenu extends Walker_Nav_Menu { function end_el(&$output, $item, $depth=0, $args=array()) { if( ‘Boats’ == $item->title ){ $output .= ‘<ul><li>Dynamic Subnav</li></ul>’; } $output .= “</li>\n”; } } Then where you call the nav menu, create an instance of your custom … Read more
This is accomplished by _wp_auto_add_pages_to_menu() (in \wp-includes\nav-menu.php) function that is hooked to transition_post_status hook. Unfortunately it is hardcoded for page post type and is not easy to extend. On other hand since it works through generic hook it isn’t hard (relatively, menus internal code is pain) to engineer analogue for custom post type.
Use a custom walker: class WPSE_33175_Simple_Walker extends Walker { public function walk( $elements, $max_depth ) { $list = array (); foreach ( $elements as $item ) $list[] = “<a href=”https://wordpress.stackexchange.com/questions/33175/$item->url”>$item->title</a>”; return join( “\n”, $list ); } } … and then call wp_nav_menu() like this: wp_nav_menu( array ( ‘theme_location’ => ‘your_registered_theme_location’, ‘walker’ => new WPSE_33175_Simple_Walker, ‘items_wrap’ … Read more
