Hi,
I have started to set up a new shop who wants to have a product filtering function almost identic to this site (they sell the same products):
shop.sf-filter.ch/mobilefilterselect.asp...M&Titel=Baumaschinen
I have been asking this a few weeks ago and been told it was possible with custom fields.
My simple question is how?
Is there anyone who can guide me a bit forward in order to solve it.

Thanks
Micke

Thanks but I don't think that is the solution here.
What I would like is a field with a scrollbar, we have like 250 different brands of machies.
I want to display three fields like on the SF-Filter page.

Filter field 1 - Brand
Volvo BM
ÖSA
Toyota etc. etc.

Filter field 2 - Model
Here I want to only display models specific to what brand of machine from field 1
(some brands like Volvo BM has got 20+ models)

Field 3 - Type / Build year / Motor model
Here we show level 3 of the filtering
Soe Models from level 2 has 40+ different types and between some types
After clicking your choice here the products applicable to the choosen type should display like usual divs.

In each filtering field should I add all Brands in no1, All models in field 2 and all Types in field 3?
Then when choosing for example Volvo BM in field 1 only the Models under Volvo BM will display in field 2?
This is how I want anyway...

Thanks, the reason I think this isn't the solution is because I don't se how I can manage to just list the three filtering fields and nothing else on the page.
I would like to just click the Webshop link in the main menu which is a horizontal meny, and then have these three fields with all filtering objects.
(The webshop link isn't displayed in public yet as there is nothing good to display yet.)

For example if I start with the most complex Volvo in the left box.
Then fill in all the models for Volvo in the custom fields editor for the field named Models.
Then I fill in all the Types etc in the last field.

I then continue with a second brand and add all models in the second field and types etc. in the third.
Continue with next brand, model etc...
I don't get how to set it up so that WHen choosing Volvo in the first box only Volvo Models shall show up in the second and then after clicking one Model only that models different options shall display in the third.

Also I don't get all three custom fields under the products.

Ok good to know that it at least will work.
But what I don't understand is how to enter all values so the filtering will differentiate between Volvo and other brands.
Here is how my fields are set up like so far:

Thanks

I don't understand how to do this.. I get an error message:
"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 'FROM bft_hikashop_product WHERE product_id IN (119,127,129,137,141)' at line 1 SQL=SELECT DISTINCT FROM bft_hikashop_product WHERE product_id IN (119,127,129,137,141)"

Setup in my hikashop filter module is as follows, Menu object ID is to a menu object in my main menu pointing to the webshop (a normal article, not a hikashop module or so).

Dear LAMF, did you solve this problem? im having exactly the same problem too, i cant get the second filter to display only things of the brand of the first filter. I will appreciate so much if you could help me, thank you!
