Hello,
we have a category called Cold Subs, then under that category few products one of them called any Two Meats,
So Customer can click on order online from the top tabs, then choose cold subs, then choose Any two meats
well it should come like a radio options either Ham and Turkey OR ham and Roast Beef OR Turkey and Roast Beef
see screenshot1

i created a custom filed like shown in screensho2 and I could not point the category to the products



so what really happen that particular custom field has been added to all the cold subs, when it has to be added to only one which is choose Two meat,
see the following sequence











as you noticed the Option has been added to all when we only need it to be added to cold Subs Any two meats like screenshoot seq4

any help appreciated

this custom field it has to go to only one product of that category, however it apply on all the products on that category ?
can you help please

Hi,

For the moment we can only restrict custom fields on categories, not on products.
So a trick to have what you need is create a new category and add this category to the desired product only and restrict the custom field on that category.

I don't understand how I'm going to create a new category. OK I'm very sorry i know how to create a new category and i know how to add the product to the category but it will look odd on the listing, we need one category that called Cold Subs.

is there more explanation?

Thanks

Excuse me, but you seem fixed on the "custom field" solution. Why not forget about it, and instead make the 3 meat combos characteristics of the "Any Two Meats" product? You'd have 3 variants then which your customers choose from, and this would be true for this one product only.

I tired the idea of adding new characteristics so its a drop down and it works, i think i have to figure how to restrict it make sure customer will choose because be default, it choose the first one, i will also go ahead and try nick idea, , thanks to both

Nick Idea works much better,
thank you Nick,

OK FOR ALL NEED IT A SIMILAR SOLUTION AND FOR ALL BENEFITS

here is what I did, create New Category , then go to product and add the product to the new unpublished category you just create it
see screenshots

Thank you Nick
