Is there a general purpose theme with blog with parent-child categories and drop-down menu?

I wonder if there is a general purpose theme that allows me to use the blog feature to have all the pages of the web site under the blog scheme and ordered by first level categories, second level categories up to third level, that I can navigate using either the blog pagination or the drop-down menu with all pages structure under blog. Does this type of theme exist in Grav?, if so please let me know which is it.
Thanks and regards.
