I’m developing an app with airtable API and then there is a page that listed items and that item has 3 filter categories, so I want to make a filter function but each filter category must can count how many items can be filtered again


example

category 1:

item 1(3)

item 2(1)

item 3(2)


category 2:

item 1(3)

item 2(2)

item 3(4)


expected result


filter: category 1 = item 1


category 2:

item 1(2)

item 2(1)


I’m stuck on that case, so can anyone help me?
