Why do Custom Nav Menus generate so many classes on list items? Can I manage this somehow?
I’m going against the majority on this one 🙂 Yes, it can be a good idea to strip it down. Personally I’m keeping only the current-xxx type classes and replacing them with active, and active-parent (for active parent or ancestor items).

Displaying Logged-In User Name in WordPress Menu

That function just registers new menus. If you want to create a custom type of menu, you need to create your own extended menu walker that would do something custom or activate any other functionality.

Add data-icon input to WordPress custom menu links

How to avoid wp_nav_menu() ID conflict?
The solution is not to call the same ‘theme_location’ more than once. Theme location is intended to represent an explicit location within the template. Just register a separate ‘theme_location’ for each separate location within the template that you want to display a nav menu.

Making breadcrumb with wp_nav_menu
I couldn’t believe there is not a single FREE plugin available that does this. So I wrote my own function. Here you go. Just copy this to your functions.php: function my_breadcrumb($theme_location = ‘main’, $separator=” > “) { $theme_locations = get_nav_menu_locations(); if( ! isset( $theme_locations[ $theme_location ] ) ) { return ”; } $items = wp_get_nav_menu_items( … Read more
