I have a section on my forum for anime, I want them organized by genre but anime have multiple genres so I want a code to organize them in multiple genres

I want each anime to be in a board if possible

I honestly don't know what will be sorted? Images, boards, categories, words, elephants, adverts?
I'm confused how you want this to work etc...

If I had each anime as a board then it will be sorting boards

But if I had each anime as a topic then it would be sorting topics

How will you specify the genre etc...

In the code, like categories except each can have multiple genres

Look at it like a filter where you filter by genre

I don't get how you want it to work?

Whether you want there to be a drop down or whatever. You need to convey exactly what you want, 'cause at the moment I have no idea!

I decided to have the Anime's as topics, so for the code the Genre's will be links or something similar and when clicked a list of anime will appear below that match the Genre clicked, the biggest part is that each Anime has multiple Genre so each anime will be in multiple lists, as suggestion would be a multidimensional array
