Help with configurable product

[Neomatrix]

Hello everyone, I have to create a configurable product.

 

The product in question is a necklace that will be formed from 3 elements.

The customers choose the colors of each of the three elements (in twenty chance) and will create their necklace.

 

Example:

 

color 1 [drop-down menu with a score of colors]

color 2 [drop-down menu with a score of colors]

color 3 [drop-down menu with a score of colors]

 

if a customer chooses the three elements in this way and order

 

1 color [black]

2 color [white]

3 color [black]

 

how do I manage the stock of the elements?

 

That is, how can I decrease the element of white stock and 1 to 2 black?

And if a color runs out, how do I do so that it is no longer with the options to choose?

 

Is there any module that allows me to do?

If you use the generator combinations I have to put an amount for each combination, but it is not what I need because I have to check the color quantity of the individual elements

 

Thanks in advance

Diego
