I am writing a theme for our team website and am currently using the categor**y** listing from `com_contact` to display a list of our team members. All members are in a single category called "Teammembers". We have an organizational structure, therefore I used the sorting fields on the contacts to sort them by organizational layers, as seen below:

I want to take this a step further, showing the titles of the organizational layers, which led me to the conclusion that I'm better off using a categor**ies** listing instead, splitting the members into separate subcategories, and showing the contents (i.e. contact items) inside of the subcategories in the top view below their respective subcategory titles (see below).

Is there any way to render the items contained inside of all subcategories in a parent category? As far as I can tell I can only render out the subcategory (titles) themselves and not their children?
