I have some problem filtering a list of things via a dropdown value.
I got clothes, both of them having a category (top, pull, jacket…) and a repeating group which doesn’t change showed things via the filtering used value, corresponding to my dropdown value.
Whenever I select a value with my “categories’s dropdown”, the repeating group always show all of my things.
@SerPounce is right, you shouldn’t need to use filter in that case imo. Although don’t forget to tick the box “Ignore empty constraints” in the Search constraints.
I see you have two conditions on your RG as well, what are those? Make sure they don’t change the data source
