Hi,
Thank you very much for the details, it helps me a lot.
I logged in to check your configuration, and I made a few minor changes, which I thought you needed:
– I removed the taxonomy terms from the results, as I assume you only want to show the casinos matching the criteria: https://i.imgur.com/aFC3IMY.png
– There were generic and post type filters enabled, which I assume you didn’t want: https://i.imgur.com/etK0U2l.png
– I have also changed the logic of the taxonomy term filters to match whever any of the checkboxes match: https://i.imgur.com/Hu2nE0v.png
Now, clicking on any of the checkboxes should start filtering the results nicely.
If you want to use the elementor container for the results, then this tutorial should help you with that.
