A Question about Filtering Variants

I have a client who sells shoes. One particular brand uses European sizing 22-47 (we are in Australia). The shoes are also allocated to HikaShop categories Women/Men/Girl/Boy.

The product has a number of variants based on colour and size. My client would like to restrict the number of variants that are available for purchase based on how the online customer navigated to the product.

For example, if the online customer followed category “\Footwear\Men\Casual”, they would only see sizes 38-47, if they followed “\Footwear\Women\Casual”, they would only see 34-40 (notice that there is an overlap). Categories “\Footwear\Girls\Casual” and “\Footwear\Boy\Casual” would both show only sizes 22-36 (duplicate sizes and overlapping with women).

The only way I can think to do this as the moment is to create 4 “products” for the same physical product, create 4 “characteristics” based on size then then create 4 sets of variants based on the combination of product & characteristic. I suppose I could use a single “characteristic” set provided that I ensured that I did not create variants for unwanted size/category combination.

Is there an easier was to filter a set of variants into groups of sub-variants based on the content of a particular characteristic and/or category membership?

Thanks Jerome,

Where is the "product | show" view? I don't see "show" as a menu option under "products" menu.

Thanks Jerome,

I understand now. I need to edit the PHP to do what I want.
