在Wordpress中显示类别列表，不包含子类别

Question

I am attempting to show categories in a list, but without displaying subcatgories. My current code is:

 <?php if (is_category()) { $this_category = get_category($cat); if (get_category_children($this_category->cat_ID) != "") { echo "<ul>"; wp_list_categories('orderby=id&show_count=0&title_li= &use_desc_for_title=1&child_of='.$this_category->cat_ID); echo "</ul>"; } }?> 

Which displays the categories nicely

but when I added a sub-category it looked like this:

Any ideas? Thanks!

Answer 1

Use get_categories() instead. https://developer.wordpress.org/reference/functions/get_categories/#Get_only_top_level_categories

It has "parent" parameter which you can set to 0 and get desired result.

Answer 2

对我来说似乎是一个CSS问题：您可能希望隐藏子类别项目，直到其被单击或悬停为止
