How can I use separator with wp_list_categories using inline list? In documentation they say (string) Separator between links. Default '<br />'. Well I guess that means I could use HTML right? I was thinking about using &middot; to connect items like I have in image but nothing happens.

enter image description here

    'title_li' => '',
    'child_of' => get_cat_ID('mycatname'),
    'hide_empty' => true,
    'show_option_none' => false,
    'separator' => '&middot;'

I tried putting something else as separator, but nothing happens so I wonder if it even works or am I missing something?

    $arr = wp_list_categories(array(
        'title_li' => '',
        'child_of' => get_cat_ID('Biljke'),
        'hide_empty' => true,
        'show_option_none' => false,
        'separator' => '-----',

    Are you sure you are using the last version of WordPress? separator parameter is introduced just some subversions ago.

It looks like the default of the style input parameter is list.

Try something like:

'separator' => '&middot;',
'style'     => 'separator',  // something else than 'list'

to override the list default.

We can see why this happens by peeking into the Walker_Category::start_el() method. There we have the following:

if ( 'list' == $args['style'] ) {
    // ...cut ...
 } elseif ( isset( $args['separator'] ) ) {
     $output .= "\t$link" . $args['separator'] . "\n";
 } else {
     $output .= "\t$link<br />\n";
  • Downvote, sorry, but this also adds the separator after the last term. I guess you could use implode to fix this but not sure how.

  • @Dev that sounds like a core bug. You could grab and edit the returned output with "echo" argument as false. Check e.g. this from the Related list, here to right.

  • Seems to be a core bug to me. Maybe someone should file a core bug report.
