Using separator with wp_list_categories

by

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

wp_list_categories(array(
    '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?

<ul>
<?php 
    $arr = wp_list_categories(array(
        'title_li' => '',
        'child_of' => get_cat_ID('Biljke'),
        'hide_empty' => true,
        'show_option_none' => false,
        'separator' => '-----',
    ));
?>
</ul>

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";
 }
