   Trying to understand if it possible to display a post that has multiple categories selected for it it. Here is an example.

   Trying to build a filtering system. Drop-down A(DD-A) has one set of categories and Drop-down B has a different set.

   When selecting option 1 from DD-A it would show all post within that category. Same for DD-B. When selecting an option from each drop down I would like the loop to spit out only the posts that have been checked with both those categories.

   Currently I can only get it to return a everything from the selected options added together vs. only the posts that have both categories selected.

   Hopefully I am making sense. I am using Ajax to return all this back on the same page dynamically on the fly so that complicates things a bit but wanted to get an idea if it is even possible before I expand on the other issues I am having.

   Any suggestions would be greatly appreciated. Thanks for the time as always.

   Thanks for the Codex reference. I had in fact looked over that page already and it was not working properly for me but I reviewed it on your suggestion just to be sure. However I did end up searching 'category__and' not working in Google and came across this post which ultimately solved my problem...
