Advanced combination possible?

[Outof]

I am building a belt & buckle store and tries to make all choises that could be in one operation. I can't really find a clever way to combine all combinations I want: Belt only, buckle only AND belts & buckle in one operation (with different belt colors and size). Is there any clever solution to combine all these choises? I have managed to do this (from combinations/drop down menu):

 

Belt color:

a)black

b white

 

Belt size:

a)Small

b)Medium

c)Large

 

No problem, but the best would be to choose something like this (if only belt, or belts and buckle, so do choose sizze and color...):

 

Only buckle:

( )

Only belt

(x)

Belt and buckle:

(x)

 

Belt color:

a)black

b)white

 

Belt size:

a)Small

b)Medium

c)Large

 

I am pretty new to PrestaShop, so I hope it  is possible without too much hassle. If I have to, it is also fine to make several product groups, if it's hard to make a clever solution to this.
