Filter element: show only existing values

-- url of the page with the problem -- : www.matabikeshop.com/

Hello.
Into filter setting, I'd like to know if there is a configuration which allows to limit the number of filter values, as a function of the product shown into page.
For example:
- I have a shoe market
- I create a page where I list all category products
- I create a characteristic called SIZE, where I insert all existing show size (from 36 to 54, for example)
- I have a filter based on SIZE characteristic, for filter shoe by a specific size number
- I inserted in all pages the SIZE filter
- When I create a category product page, I desire to limit the number of SIZE filter elements, by only the size present into the category of the page opened.

This kind of configuration is possible or I have to modify Hikashop PHP files?

Thanks for your support.

Thanks for the reply, but in my site this isn't true:
- I created a test characteristic, with 3 values (COLORS => WHITE, BLACK, BLUE)
- I associate to one product only 2 values of the characteristic (PRODUCT => COLOR-WHITE, COLOR-BLACK)
- I created a test filter linked to COLOR characteristic; I published this filter on all product categories pages; the product with COLOR characteristic is present in only one page but I see all characteristic values in all pages, when I have to see this filter (or its values) only in the page that contains the product with COLOR characteristic ... or at least I have to see only the color characteristic values associated to the product (then, WHITE and BLACK).
Is this behavior automatic in hikashop filters or I have to set something?
Do I make myself clear?

Thanks for your support.

Really thank you !!!
I'll follow your instruction: I'll let you know the result of my operations.
Thanks !!!

Hi.
I'm sorry but it doesn't work: my filters show also the characteristics not associated with any product.
I made a test: I create a new color called 00-NEW. This color, obviusly, is doesn't associated with any product: I expect not to see its. But it doesn't happen: I see it inside my color filter list.
This is my site configuration:
- IMAGE 1: my HIKASHOP filter module configuration. I set the MENU parameter with the menu id where is possible to see the filter
- IMAGE 2: the menu item where is shown the filter module, on the left side of the page. In this page, is possible to see the product of category BICICLETTE
- I associated the characteristic COLORE to this product category
- IMAGE 3: the filter configuration. I create a filter called COLORE (=color in english); I set the category BICICLETTE, the same of the menu; the characteristic associated is COLORE (parameter on the right of the image), I included the subcategory;
- IMAGE 4: the characteristic COLORE, where is possible to see the test value 00-NEW
- IMAGE 5: the hikashop filter, that doesn't limit the list with only filters value associated with one product at least. You can see the value 00-NEW, that it doesn't associated to any product.

Where's the problem?

What can we do for test together the behavior of my filters?

Thanks for you support.

Bye.

It works ... incredibile !!! Really thank you !!!

Characteristic filters work correctly but now I have problems with CATEGORY filters, insiede the same filters structure: probably there are another template customization that crash the system.

Could you make another check?

I attached three images:
- one about the filter configuration, where you can see where I selected TELAI category;

This is new for me ... I never thought about this ...
Here's the error:

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-Misura_211 ON Brand-Misura_211.variant_product_id=c.product_id WHERE (b.product' at line 1 SQL=SELECT DISTINCT b.* FROM #__hikashop_product AS b LEFT JOIN #__hikashop_product AS c ON b.product_id=c.product_parent_id LEFT JOIN #__hikashop_variant AS Brand-Misura_211 ON Brand-Misura_211.variant_product_id=c.product_id WHERE (b.product_published=1) AND (b.product_type = 'main') AND (b.product_manufacturer_id IN (400)) AND ((b.product_access = 'all' OR b.product_access LIKE '%,9,%')) AND ( Brand-Misura_211.variant_characteristic_id IN (83) ) AND ( c.product_quantity!=0 ) ORDER BY b.product_name ASC LIMIT 0, 40

Let me know.

Really thank you.

Really thank you !!! It correctly works !!! I renamed all filters and now they work correctly.
My mistake, but it would never happen with a control system into filters creation ... I'm kidding !!!
Really thank you for the support !!!

Best regards !!!
