wp_nav_menu: List only 2nd level (separate submenu)?

Of course, the solution would be to hide that child category if you didn’t want it to show, meaning that the current-menu-parent class would still show on the parent.

Hey there, this walker works great, i just wanted to ask if there is any way you could help me to modify it a bit. I am kind of new and i can’t seem to make this work, i’m trying to get this to work for two days now.

I want the walker to only show the current submenu, so i have :

Parent 1
– Child 1
– Child 2
Parent 2
– Child 3
– Child 4
– Child 5
Parent 3
– Child 6

Now if i am on the page Child 1, i see Parent 2’s Childs, and i want it to be like this, when i’m on Parent 1`s childs the menu to show:

Parent 1
– Child 1
– Child 2
Parent 2
Parent 3

When i’m on Parent 2’s childs the menu to show:

Parent 1
Parent 2
– Child 3
– Child 4
– Child 5
Parent 3

And so on. Is this possible? if it is, could you at least give me a hint or something towards the right way?

Thank you

dantdr –
Sounds like you’re not quite in the right place w/ this thread.
Try rendering the whole menu with the regular wp_nav_menu function and then hiding what you don’t want to see w/ some CSS.

ul.sub-menu {display:none;}
li.current-menu-ancestor ul.sub-menu {display:block;}

something like that.

i just managed to do what i needed with the help of danieliser`s function, thanks

Another subnav walker that seems to work well in a few quick tests:

Found via

Here’s a walker I made to just display child menu items of the current top level one (even if they’re a few deep). Not perfect (it still shows empty

elements), but thought I’d share in case it helps anyone.

Ta to everyone on this thread for the posts too!

Also, the Gecka Submenu (https://www.ads-software.com/extend/plugins/gecka-submenu/) plugin works well.

Hi all,

this works for me:

on wp-includes/classes.php row 860

change from
if ( ($max_depth == 0 || $max_depth > $depth+1 ) && isset( $children_elements[$id]) )

to
if ( ($max_depth == 0 || $max_depth >= $depth+1 ) && isset( $children_elements[$id]) )

obviously creating a custom walker duplicating
the function “display_element” containing the modified code in order to avoid editing the core…

here it is:

class Custom_Walker_Nav_Sub_Menu extends Walker_Nav_Menu {

function display_element( $element, &$children_elements, $max_depth, $depth=0, $args, &$output ) {

  if ( !$element )
   return;

  $id_field = $this->db_fields['id'];

  //display this element
  if ( is_array( $args[0] ) )
   $args[0]['has_children'] = ! empty( $children_elements[$element->$id_field] );
  $cb_args = array_merge( array(&$output, $element, $depth), $args);
  call_user_func_array(array(&$this, 'start_el'), $cb_args);

  $id = $element->$id_field;

  // descend only when the depth is right and there are childrens for this element
  if ( ($max_depth == 0 || $max_depth >= $depth+1 ) && isset( $children_elements[$id]) ) {

   foreach( $children_elements[ $id ] as $child ){

    if ( !isset($newlevel) ) {
     $newlevel = true;
     //start the child delimiter
     $cb_args = array_merge( array(&$output, $depth), $args);
     call_user_func_array(array(&$this, 'start_lvl'), $cb_args);
    }
    $this->display_element( $child, $children_elements, $max_depth, $depth + 1, $args, $output );
   }
   unset( $children_elements[ $id ] );
  }

  if ( isset($newlevel) && $newlevel ){
   //end the child delimiter
   $cb_args = array_merge( array(&$output, $depth), $args);
   call_user_func_array(array(&$this, 'end_lvl'), $cb_args);
  }

  //end this element
  $cb_args = array_merge( array(&$output, $element, $depth), $args);
  call_user_func_array(array(&$this, 'end_el'), $cb_args);
 }
}
