How to filter CMS collection dynamically?

Hi everyone,
I would like to create a page with a dynamic filter for my CMS collection items.
Basically I have collection items named Projects in which there is a multi reference field of a Project Category collection item.

What I’d like to do is to be able to filter Project results in just one page by selecting/de-selecting the Project categories that I want to show. I found this example but I’m not sure if it works with CMS collection Filters as well.

Can you help me figure out how to do it?
Thanks

There is an integration called MixitUp, they also have a tutorial for CMS content filtering

I was reading their documentation but it seems that the filter doesn’t work with multireference collection, which is my case
