Hi

I need to setup a shop for a jewelry store. Nothing too big, but my client has a specific question and I don't know if this is doable.

Client sells rings, a ring has different sizes (50,52,54,56,...) but she doesn't have all sizes in stock (too much).
She wants a dropdown box with all the sizes and the size which is in stock needs to be bold and in a different color. This way the client sees which ring is in stock.

like this:

50 (bold/color because in stock)
52 (plain text)
54 (plain text)
56 (bold/color because in stock)

Any idea if this is possible to achieve?

thx
