On my site/blog I have multiple categories organized in parents and children of each other. They don't work as I originally thought. Here is how part of it is set up:
-Super Smash Bros.
Child Categories For This Parent:
-Super Smash Bros. Melee
-Super Smash Bros. Brawl
Melee and Brawl are titles part of the SSB franchise. If an article I write only applies to Brawl, I would apply it to that. If an article I write applies to all Smash games, I would apply it to the parent.
I would think that if someone chooses on my site to view all posts with "Super Smash Bros." as the category, it should view all posts from that category only. This is the case - good.
Now if someone chooses to view all posts with the category "Super Smash Bros. Brawl", it only shows posts in Brawl, and nothing else. I would think it would show all Brawl posts, and all generic Super Smash Bros. posts, aka moving up the ladder.
The reason I don't apply posts that pertain to all games to just every game at first is because in the future I would add another Super Smash Bros. game when it comes out, and when that category is added, I would like all those generic Super Smash Bros. posts to also apply to that category.
I hope this makes sense, is it possible to do?
