https://your.domain/admin/site_settings/category/all_results?filter=top%20menu
from which the order of appearance of the tabs is determined, and thus the first one displayed by default
Choose the items that appear in the homepage navigation, as well as their order. Example: latest|new|unread|categories|top|read|posted|bookmarks
and on the other hand, the “desktop category page style” parameter allows you to choose how this category page is displayed.
