I have set up my wordpress site so that each page displays posts from a specific category. Each page would have a left column with the post titles belonging to that category. However, I would like it, when you click on a post, for that menu to remain. So it must be present in the single post page.
Rather than write a bunch of if statements and wp_query's i was wondering if anyone knew how I could make it so that other posts belonging to the same category as the single post were listed. There are over 5 categories, hence why I am looking for something simple. Preferably something that would work for both the page template and the single post template.
