How to retrieve only certains attribute's options for a given attribute set, in admin, in new product and edit form ?
For Example, two attribute set (e.g., set-1 and set-2).
In each, color attribute is assigned and color has options (e.g., blue, yellow, green, red).
The goal of the question is to be able to set 'blue' and 'yellow' as available options of color in set-1,
and to set 'green' and 'red' as available options of color in set-2,
instead of having all options.
Any suggestion is welcome.
There is no way to do this out of the box (honestly, I have no idea why would you want to do that, but anyway...).
This is just an idea, I don't have much code for it.
You can control the options from a dropdown attribute if you use a custom source model.
Here is a tutorial on how to create a product attribute with a custom source model.
I would suggest creating a simple CRUD module where you manage your colors. Each color you add should have a multiselect field that contains all the attribute sets and you can select for each color in which attribute set to go.
Then, in the source model, in the getAllOptions method, just check the current attribute set for the product and display only the colors assigned to that attribute set.
The downside is that when you create a new attribute set that contains your attribute you will have to go through all the items in your CRUD module and assign them to that attribute set.
But you can overcome this by adding a mass action to the grid of your module that allows you to mass assign or unassign colors to/from an attribute set.
