Category 2 Category 21 Category 22

You need to use a function that lists the children of the passed parent_id, then call it recursively so that it prints a tree. For the initial call, you would pass it the root id, usually 0 or -1. There is a great Sitepoint article that details how to do this. Read http://www.sitepoint.com/article/hierarchical-data-database
