E-Shop Dependent Options?

sorry if this has been asked before but I could not find it

I am developing a Lingerie store and need to dependent options

1) color - white
2) Cup - a,b,c,d,e,f,g,
3) size - 32,34,36,38 etc

so if the white bra has a,b,c cups in 32,34, & 36
but no d cups in any size

how would this be done??

Hello Mary,
Thank you for using our EShop shopping cart extension. The feature that you required is for option combination. This is an advanced feature which we have plan to add it. However, it is really complex to implement and we have still not had it ready.
I will focus to develop and will try to release it soon.
Once it is ready, I will let you know.
Sincerely, Giang
