Hola @SLP_Nerdcast , I’m glad to see that my idea is still useful to many people.
I was going to tell you that you can copy my APP demo and check how it was created but I’m noticing that some component or some improvement/change made by Glide broke something and I need to verify and fix it.
But in the meantime, the friend @NunoDel wrote a good step-by-step document to understand my procedure. To be honest, I’m going to use it to remind myself of all the things I did months ago on that APP, thanks Nuno! 
The current caveat with this technique is the number of edits consumed. If you use it in an APP with many signed in users, your edits will affect your paid plan and quota (it can be worse than a Pac-Man). Instead, if your users are Visitors, there is no problem about it.
Your plan B is to use Glide’s native filters. When I created this APP demo, Glide’s pricing policies were different (there were no edit charges) and advanced filters didn’t exist but currently, the situation is better if you want to use their native filters.
Saludos!
