Hide/Show nested repeats

Hello Wappler experts.

I was following this great manual - https://docs.wappler.io/t/nested-repeat-regions/5165 and in overall it went just fine: I was able to re-create what’s shown in the lesson in my app, but in my case those nested repeats (repeat2 in the lesson) might be hundreds of entries.
And my question is: is there is an option or a workaround how I can hide/show specific repeats?
