WooCommerce - I have an e-shop with board games and I have an product attribute “Players count”. I need a filter with this behavior:
Customer sets the filter to “2 - 5 players”,
the filter will show all the games they have players count like: 1 - 3 players, 3 - 6 players, 3 players, …
The best way is range filter like for price.
Ideal variant is Bricks native AJAX filter (and some custom code).
If you have a custom field on the product for player count, you can use the new Filter - Range element.
Sadly, it’s product attribute, not custom field.
Aren’t attributes just taxonomies?

As long as you can query it with Bricks dynamic data you should be able to use filters.

I can filter by players count with checkbox-like filters. But I need to achieve this behavior:
Customer sets the filter to “2 - 5 players”,
the filter will show all the games they have players count like: 1 - 3 players, 3 - 6 players, 3 players, …
Pseudo code:
game_players_count_from <= filter_players_count_to AND game_players_count_to >= filter_players_count_from
Try the Filter - Range element.

No. 
Product attributes are in postmeta table in some structure format:
@GrowPlugins Range filter accepts only custom fields, I can’t set it up to accept product attribute.
It sounds like you will need to create a custom PHP function to query your data, and then call it as Dynamic Data using the echo function ({echo: some_function()}). But the exact code you will need to use I don’t know.
I know you will need to use unserialize() to convert that data into an array.
I haven’t tested this, but you may be able to use the meta query setting to get what you want. You will need to know how the meta data is stored.
