Additional taxonomies or queries

Hey Team,

I need your help on this. My client needs additional taxonomies. I’m pretty sure this is going to require some custom coding but im hoping you could point me in the right direction to be able to display my projects with these additional categories or queries? See what I’m asking about here https://snag.gy/xYa0R9.jpg or the website is here https://www.donorschoose.org/donors/search.html
