How to list categories and subcategories in WordPress

How to display all CATEGORIES and SUB-CATEGORIES in wordpress if a category having 0 posts also. I tried but it is displaying categories which are having at least 1 post in a category . I want to display categories which are having 0 posts also.

Thank You

  • See the get_categories function, there is a parameter called "hide_empty". For instance:

    <?php $cats = get_categories('hide_empty=0'); ?>
