Create a Custom Filter for City & Area

-- HikaShop version -- : 3.2.2
-- Joomla version -- : joomla 3.8.2

Hi,
I am trying to create a custom filter that can filter product by City & Area within the City. Is there any extension that can do this because previously i was do this by using cherry picker however cherry picker seems like not available anymore so is there any similar extension tat can do customise filter? or is there any possibility that custom field of hikashop can achieve this? i am trying to create a filter that exactly like this

i tried this with custom field of hikashop but when i pick city A, the area from City B will still appear at the dropdown list, so how can i achieve only area from city A will appear after i choose City A?

Hi, thanks for the reply.

But i tried with filter of hikashop business , when i selected City A, area from city B or City C also appeared in the next drop down. how can i define the Area is Belong to which city using custom field. Example:-

When select City A, The dropdown for Area will show area A, area B, area C
When select City B, the dropdown for area will show area D, area E, area F?

Hi, below is my config, but apparently this method can only make it 1 product having 1 set of data (1 product assigned to one city).

how can i create one product and assign it with multiple set of data/city of custom field so that when i create a filter module it can dynamic showing:-

When select City A, The dropdown for Area will show area A, area B, area C
When select City B, the dropdown for area will show area D, area E, area F?

Hi, thanks for the reply.
as the screenshot attached, there is condition that one product is selling in multiple city, how can i group the area to the city they belong so that when i pick city A, area from City B wont appear in filter?
