Filter multiple galleries loaded via code

I’ve created a page template to automatically load in any FooGalleries that have been created using the following code:

$galleries = array();
            $galleries = foogallery_get_all_galleries();
            foreach ( $galleries as $gallery ){
                foogallery_render_gallery($gallery->ID);
            }

That part is working great – exactly how I want it to.

What I’d like to do is add in a filter. I know it might be doable in the PRO version, but I want to verify before making a purchase. Every gallery would be assigned a category of either Residential, Commercial, or Place of Worship.

So, ultimately, I want the page to function like this – Filtered Page – but with multiple galleries instead of just images.

The page I need help with: [log in to see the link]
