get_the_category() function used to retrieve categories array of a post, and array_shift() function used to get the first item of an array. You possibly need this – function ux_breadcrumbs() { if (!is_home()) { echo ‘<a href=”‘; echo get_option(‘home’); echo ‘”>’; bloginfo(‘name’); echo “</a> » “; if (is_category() || is_single() ) { if( is_category() ) { … Read more
If its a matter of adding icons as per the classes, add it from the back-end and use that class to assign icons through css.
I found the answer after I typed out the question so I’ll post it at the same time.

What you’ll need to do is use get_ancestors(). Pass get_ancestors() your current page ID, and then search the resulting array for the menu item ID. If the menu item ID is in the array, set the class to active.
wp_nav_menu_items aren’t mentioned in the codex, so there are no concrete description on how to use it. wp_nav_menu_items can be found on line 347 in wp-includes/nav-menu-template.php $items = apply_filters( ‘wp_nav_menu_items’, $items, $args ); within wp_nav_menu. In the codex, it states the following Displays a navigation menu created in the Appearance → Menus panel. So this … Read more
Not sure if this is robust enough, but it shows basic traversal through menu to look for current post first then for its menu parent: /** * @param mixed $menu * @param int $post_id * * @return WP_Post|bool */ function get_menu_parent( $menu, $post_id = null ) { $post_id = $post_id ? : get_the_ID(); $menu_items = … Read more
To center the menu just edit this css code : .main-navigation ul.nav-menu, .main-navigation div.nav-menu > ul { text-align: left; } to : .main-navigation ul.nav-menu, .main-navigation div.nav-menu > ul { text-align: center; }
As per comments: this is what the Customizer API is for. In the case of the header there are a dozen parameters to tweak the behaviour with. Like this: $defaults = array( ‘default-image’ => ”, ‘width’ => 0, ‘height’ => 0, ‘flex-height’ => false, ‘flex-width’ => false, ‘uploads’ => true, ‘random-default’ => false, ‘header-text’ => … Read more
class Themeslug_Page_Navigation_Walker extends Walker_Nav_Menu { function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output ) { $id_field = $this->db_fields[‘id’]; if ( !empty( $children_elements[ $element->$id_field ] ) ) { $element->url = $children_elements[$element->$id_field][0]->url; } Walker_Nav_Menu::display_element( $element, $children_elements, $max_depth, $depth, $args, $output ); } } This did the trick.
