Ok, step by step.

1. I installed the Newspaper theme, and chose “Pulses Pro” pre-made website. I activated “Design only”.

2. I chose “Cloud Templates”, then clicked on “Category Template” and edit it with TagDiv Composer.

3. Now the screen changed to the Tagdivie Composer Interface. The main category page is designed like this:

4. Situation: When my category has some sub-categories, there will be a list of sub-categories, right below the category description. Like in this live web link:

https://www.banyantimes.com/section/business/

However, if my category has NO subcategories, there is a menu list of other same-level categories, which I do not like, as in this live web link:
https://www.banyantimes.com/section/sports/

5. Questions: How can I remove the menu in the second case where the category has no sub-categories?
Or, what are other options I can enter for “Categories to show when display as list” in TagDiv Composer?
