The original topic has been closed, so I’ll start a new one.
As described at https://developer.projectdmc.org/reference/functions/wp_list_categories/
you need to specify the option include and the category ID.
For a clear example, see the following page (Japanese):
https://wp-design.jp/template-tags/311.html#index_id10
However, if 12 is the parent category and that has 13, 14 and on are child categories, and you want to display all categories, you must write
[categories include=’12,13,14′]and all categories. If the number of categories increases, you will need to manually add categories as they come up.
I(ChatGPT) created a plugin that does the same thing , listing only the categories you specify. I’ve made it so that you can easily specify options. No warranty. (Japanese)
