Can wordpress filter posts according to their categories? For example, if i have some categories, A, B, C, D...etc...
And I wanted to query all the posts that are filed under A, C, AND X.
notice that i said AND, not OR.
so if a post is filed under X, but not also under A and C, that post shouldn't be displayed.
I believe this feature would be very helpful for my visitors and for me also to organize my website's content.
so can that be accomplished with WordPress?
