How to filter items in a repeating elements in repeating container

I have a repeating container of Symptoms Category(Cold, Illness, Covid). Within each category, I have a repeating container of Symptoms. When filtering with "category is “Cold” I can see the results is filtered(as show in Loom). When I want to use the of Symptom Category, it shows nothing. I am stuck in this for 4 days, can anyone please help me? I wish to get symptoms with category “Cold,” “Illness”, “Covid” in their corresponding containers.

Can Weweb give a tutorial on how to deal with inputs(&multiple inputs) and displaying data in repeating containers within repeating containers?

Hello @whcmeduk,

It’s an issue on our side, for now I suggest you to use filterbyKey function for your collection. It will work
