Jak zrobić w preclu na WP, żeby wyświetlały się kategorie

[Elegant]

Zrobiłem sobie precel IT, do którego można dodawać ciekawe artykuły z branży IT, jednak z uwagi, że liczba wpisów jest jeszcze niewielka (sam też niewiele jeszcze napisałem), chciałbym żeby wyświetlały się wszystkie dostępne w wordpressie kategorie a nie tylko te, do których został dodanych jakiś wpis. Czy można to gdzieś ustawić? Nie bardzo widzę taką opcję

Najprościej utworzyć własne menu ze wszystkimi kategoriami i wstawić je jako widget.

 <?php wp_list_cats('all'); ?>

To albo wstawiasz w odpowiednie miejsce w swoim sidebar.php albo tworzysz sobie tam nowy blog z kategoriami, ale nie używasz już wtedy widgetu

U mnie w sidebars.php jest trochę inaczej:

<?php
// tokens
 $ew = '<!-- end_widget -->'; 
 $bt = '<!-- begin_title -->';  
 $et = '<!-- end_title -->'; 
 $bi = '<!-- begin_id -->'; 
 $ei = '<!-- end_id -->'; 
 $bc = '<!-- begin_class -->'; 
 $ec = '<!-- end_class -->'; 

 $sidebars = array(

  'default' => array(
  'name' => __('Primary Widget Area',THEME_NS),
  'id' => 'primary-widget-area',
  'description' => __("This is the default sidebar, visible on 2 or 3 column layouts. If no widgets are active, the default theme widgets will be displayed instead.", THEME_NS)
),

'secondary' =>  array(
  'name' => __('Secondary Widget Area',THEME_NS),
  'id' => 'secondary-widget-area',

),

'footer2' => array(
  'name' => __('Second Footer Widget Area',THEME_NS),
