Search Variables in Drop Down

[SpecTech]

Hi,

does anyone know how I can have searchable variables appear in a drop down exactly like this actinic website (ask the expert search on homepage):
http://www.lessbounce.com/

for example I have a variable for each possible size a product comes in:
28A = true
28B = true
28C = false

the reason behind doing it this way is so I can have true on multiple variables if I did:

size = 28A

you can only have 28A and not have it available in size 28B

when I then add these to the search field they appear as individual options, is there any way to get them all in one drop down?

Okay Solved, wasnt an actinic friendly thing so used a custom form and a bit of javascript.
