@lonchbox

Thanx for this gist, it help me a lot, but how can I also use the current-menu-item class in the

  • ?

  • @smhmic

    @lonchbox - To allow a class for the current menu item, change the first line in start_el() to something like:

    $output .= '<li'.($item->current ? ' class="current"':'').'>';
    
    @Jakobs-House

    great stuff!! thanx for that...
    is there a possibility of adding the level nr. ?

    @Jakobs-House

    ok found it :)
    just added to the li output from smhmic

     'level-' . $depth . 

    (just dont know how to post a code here in github comment field :))

    Hi,

    Thank you for the code. But I can't insert new classes in css classes (optional)
