I am using Isotope jquery plugin to filter/sort posts in Wordpress but to correctly filter the posts into the right order I have needed to output each category one after the other. To do this I've created one custom query for each category (4 categories in total, therefore 4 queries). You can see my working code here: http://pastebin.com/LTDmbbLf.
I would like to convert these 4 queries into just one query but this one query must display these 4 categories one after the other (like it does currently).
The reason why I want this, is because I'd like to add Infinite scroll functionality to grab the next batch of posts regardless of what category they are in. In order for this to work I need to add pagination and figured pagination wouldn't work correctly with 4 separate loops. However, if anyone can implement pagination into my existing code without having to re-write it then I'm all ears.
