Until now, I just avoided using them, but with my calendar project where others will take over, I have decided to use the widgets, in order to make it easier for others to maintain, expand or change themes.
Earlier I have built my themes from almost scratch and one of the things I liked was that the entire category list is visible, although there are no posts.
In the good old days it was just
<? Php wp_list_categories ( 'hide_empty = 0 & orderby = id');?> and, the whole list was shown in the order that was intended.
In the Widget "Categories" I can only select a title, show drop down, show numbers of posts, show hierarchy.
What is wrong?
